Here are described changes, made in original Astrolog 5.41.

To distinguish changed and original versions, changed versions have 
additional letter after number. Last changed version is named
Astrolog 5.41a.


Changes made in code:

Astrolog 5.30a
----------------
Actually here I moved all my previous changes from Astrolog 5.20k to new 
original version 5.30. Most new switches are accessable in Windows version 
through menus.


1. In graphichs wheel chart between house (sign) cusps and house numbers
(sign icons) are ADDED icons of DISPOSITORS.


2. In graphics wheel charts is CHANGED DASHENNESS of aspects lines:
now aspect line is solid if orb of real aspect is below 1/4 of
maximum allowed orb for current aspect (not fixed 2 degree undependent
of allowed orbs).


3. In comparison grid charts (both text and graphics) with -rt switch
is now used DIFFERENT planets RESTRICTION SET for both input charts,
second set is transiting planets restriction set (originally in this
case was used for both charts one restriction set from first chart).


4. Added alternative way to restrict stars.  Originally if all stars are 
unrestricted, using of -U switch caused garbage of graphich wheel chart 
from aspect lines between all stars, also star orbs are fixed 2.0 deg.

In version 5.30a are added switches YU, YUo and YUa.
-YUo <value> - set aspect orbs for stars (in degrees), default 1.2 deg
-YU - switch on/off alternative star restrictions.
-YUa <value> - number of aspests taked into account to unrestrict stars.
      For example:
       -YUa 1  -  all stars NOT CONJUNCT allowed objects are restricted,
       -YUa 2  -  all stars NOT CONJUNCT OR NOT OPPOSED allowed objects
                  are restricted etc.
Note, that switch -YU itself don't allow any stars, one can use -U switch 
undependent of -YU. In Windows version these settings are available in menu 
"Chart Settings".
Stars needs really very narrow orbs, about 1 deg or narrower, and in 
version 5.30a orb additions of objects aren't used for aspects with stars,
because orb-addition may be in this case greater than orb itself.


5. In case of comparison charts and parallel-antiparallel charts all orbs
and orb-additions are TEMPORARILY DECREASED and RESTORED after calculating 
of chart. In case of parallels-antiparallels also powers of aspects are
decreased 4 times. Now no need to change aspect orbs in case of comparison
or parallel-antiparrelel charts - they are automatically decreased.
New switches -YOc <value> and -YOp <value> sets coefficients of temporary 
decreasing. For example:
-YOc 2.0  - set for comparison charts 2 TIMES narrower orbs (default 2.5)
-YOp 5.0  - set for parallel-antiparallel charts 5 TIMES narrower orbs
            (default 6.0)
Best way seems to use these switches in astrolog.dat file. To disallow this
option enough to set both coefficient to 1.0. In Windows version these
switches are available in menu "Aspect Settings".


6. Changed aspect powers calculation. With -a and -a0 switches INSTEAD
FIXED POWERS of planets given in astrolog.dat file, powers CALCULATED
with -j switch are used (really, only positions part). In case of
comparison charts for natal chart are used calculated planet powers,
for transiting planets respective transiting powers from astrolog.dat,
for progressed planets calculated planets powers. If compared two separate
charts, calculated different powers wor both charts are used. Changed are 
also power calculations with -T switsh, now "-Tn"  and "-rt infile now" 
gives same result.


7. Planets powers calcultions are overwritten.

Changed calculation of position powers: ADDED decreasing of power,
if planet is in FALLING or DEBILITATING sign or house. In aspects
powers sum calculations now is used POSITION POWERS of planets, given
in first column, INSTEAD FIXED from astrolog.dat - now powers of aspects
depends from planets position powers.

Astrolog routines gives possibility to include in powers calculations
also addition of power, if planets are in reception. Now planet powers
are calculated in separate routine used for both -a and -j switches.
Taked into account are: ruling, exalting, fall and debilitating in
sign and house, also RECEPTION for main planets. As earlier, planet
give addition to rulers through sign and house, also house cusps give
addition to sign rulers.

MAIN CHANGE:
Astrologers are using two definitions of house ruler:
  1) classical (natural ruler) - ruler of 1st house is Mars,
     ruler of 2nd house is Venus etc.
  2) accidental (situative ruler) - ruler of house is planet, which
     rules sign where is house cusp.
Contemporary astrologers uses mostly situative rulers, and natural 
rulers are used as auxillary.
Original astrolog uses in power calculations only natural rulers.
In current version influence through houses are devided to two parts:
   1)  1/2 is given to natural rulers.
   2)  1/2 is given to situative rulers.

To planets total powers are added powers of of parallels and antiparallels.
Orbs and orb additions are temporarily decreased (look point 5) and
aspect-powers decreased 4 times (for parallel 0.25). It is actually small
addition to total powers.


8.Changed -j -X graphics chart: situative rulers hierarchy is added,
so now here is three hierarchy: sign dispositor, house natural dispositor
and house situative dispositor.


9. In standard text chart added column with planet ruling, exalt etc
in house, corresponding to situative house ruler. So after house number
in column Rul. now are two letters - first one corresponding natural ruler,
second one corresponding situative ruler.


10. Added animation of graphics secondary progressed charts:
      astrolog -i infile.in -pn -X   and
      astrolog -i infile.in -p mm dd yy -X


11. Changed info-border in graphics wheel charts. In case of progression
chart are displayed natal data, and also time and Julian day, where chart
is progressed. In case of comparison charts are displayed info of both charts
and for second chart is marked which cahrt it is: comparison, transit or
progressed. These data changes respectively in case of animation.


12. Fixed bug, where applayng-separating of comparison charts natal -
progressed and natal - transit was wrong.  Now with -rt and -rp switch
nahal chart planets velocities are made zero, and -rt (or -rp) with -a
switch give correct applay-separate aspects (like -T switch).


13. By analogy with sign's powers calculations added house's powers
calculation. (in DOS version switch -j0).


14. In aspect configurations list (in dos version switch -g0) added
"Mystic Rectangle". Aspect configuration list is now printed out also
with aspect list (switch -a0). "Mystic Rectangle" is described in 
lesson.asp by L. M. P. McPherson, available on my homepage.


15. Original Astrolog has ability to display positions of 177 Arabic Parts.
But there aren't displayed aspects to other objects. In version 5.30a
is added possibility to show only Parts, which have some aspects with
other unrestricted objects, and to show these aspects. Orbs can be set by
user.
Here are added new switches YPo, YPa and YPs.
-YPo <value> - set aspect orbs for Arabic Parts (in degrees), default 1.0 deg.
-YPa <value> - number of aspests taked into account to display Parts,
               default 1.   
   For example:
       -YPa 1  -  all Parts NOT CONJUCT allowed objects aren't displayed.
       -YPa 2  -  all Parts NOT CONJUCT OR NOT OPPOSED allowed objects
                  aren't displayed etc.
       -YPa 0  -  switch off this option, display like original version.
-YPs <value> - number of aspests displayed for every Parts,
               default 5.
   For example:
       -YPs 1  -  all CONJUCTIONS are displayed,
       -YPs 2  -  all CONJUCTIONS and OPPOSITIONS are displayed etc.
       -YPs 0  - switch off this option, display like original version.

In Windows version these switches are available in menu "Chart Settings".
Note, that these switches are undependent, that mean in case -YPa 0 -YPs 18
Astrolog 5.30a display all aspects of all Arabic Parts.


16. Added new graphcs outputs:

The idea of the "flower" was given by Theodore Natsinas the author of 
"Astro - Chart", (1992) publihed by Compupress - Greece. Any comments or 
opinions about it can be mailed to: tednat@compulink.gr

a) Tension - harmonic chart. On grapchisc wheel chart instead standard aspects 
distribution of tensions/harmonics are displayed. Over the Zodiac for every 
point is calculated sum of powers of all aspects to this point, oppositions 
and squares has negative influence, trines and sextiles positive (conjuctions 
aren't taken into account as neutral). Tension points are placed near centre, 
harmonics near outside of wheel. Result is like some flower, where petals 
shows harmonic areas, intervals between petals shows tension areas. Ring in 
centre shows neutral level. This chart can be reversed, that mean, "petals" 
shows tension areas. 

b) Aspectation chart. By analogy, for every point is calculated sum of all 
allowed aspects to this point, but now all influences are summarized with same 
sign. Now petals shows more aspected areas in a chart.

Both charts can be rescaled.

Allowed are also analogious comparison charts. Here is two differences:
a) In case of comparison charts orbs are temporarily decreased (look point 5
above), so "flower" can be with very sharp petals, but one can use -YOc switch 
to smooth picture. -YOc 1.5 seems enough.
b) In different comparison charts different planet powers for outer planets 
ring are used: for comparison (-r0) planet powers are calculated (look point 
7 above), for transit planets respective transit influences from astrolog.dat 
are used. Powers for inner planet ring are calculated like for hatal.

New switches:

-Xa 0        -  switch off new graphics (also -X made it)
-Xa 1        -  display tension/harmonic chart, tensions in centre.
-Xa -1       -  same chart but reversed, tension outside.
-Xa 2        -  display aspectation chart.
-YXc <value> -  rescale both charts, value between 0.2 and 4.0, default 1.0.

In Windows version these switches are available in menu "Chart Settings" in
separate box.

Text output for such charts is added to standard influence output (-j0).
After every allowed object is printed four columns. First two columns shows 
respectively harmonics and tensions in point, where planet is placed. Third 
column (sum of first two) shows summary tensions/harmonics in point, where 
planet is placed, fourth one total aspectation of this point. Note, that these 
aren't planet powers but parameters of respective point on chart. In other 
words, third column correspond to -Xa and -XA switches, and fourth one 
correspond to -Xc switch.


17. Corrected calculation of Alcabitius house cusps. Thanks to Per Dahlin
(pdahlin@tripnet.se) who sent me definition of Alcabitius houses.


18. Changed calculations of house cusps in Polar Zone. In some situations
in Polar Zone (named by Per Dahlin "circumpolar situations) pair ASC - DES
must be reverted, because Zodiac is ascending in reverted direction.
Discussion in alt.astrology shows, that exist two points of view to flipping
also MC-IC:

1) MC is defined as upper culmination, then MC - IC aren't flipped, but MC
is under horizon.
2) MC is defined as culmination above horizon and MC - IC must be flipped.

In most graphichs wheel charts with reverted Asc, MC and houses order,
Asc is placed to right. Then Zodiac and planets saves his placement.

Because exists two points of view to flipping of MC in polar zone, in
this version user can select, flip in circumpolar situation only Asc or 
both Asc and MC. This option is controlled by switch -YH (or _YH, =YH).
Default setting is =YH (that mean, flipped are both MC and Asc). If one 
want flip only Asc, best way is add to astrolog.dat line:

_YH

Because use of this switch is very rare, this switch isn't controlled 
under Windows menus.


19. Added Uranian Proserpina. All info I have about Proserpina is available
on my homepage. So Astrolog 5.30a has 9 Uranians instead original 8.
Proserpina is Uranian #8, (obj. #40) and last Uranian Poseidon is obj. #41. 
Remember about corresponding changes in astrolog.dat. 


20. Added 25 fixed stars, listed in file astars.txt. Because added stars
have apparent magnitude greater than 2.0, colors of star printout are changed. 
Stars brighter than (less than) magnitude 1.0, are red, with magnitude between 
1.0 and 2.0 are orange, and stars with magnitudes more than 2.0 are dark 
red. Star name "Orion" is changed to Alnilam (epsilon Orionis), because one 
of added stars Mintaka (delta Orionis) is another star from Orion's belt 
(see also helpfile of Astrolog, description of switch -U).


21. In Windows version increased (2 times) screen buffer, because some new
text outputs doesn't go in old one. 


22. Added new feature. In original Astrolog user can customize rulership of a
planet using switch -YJ. That mean, changed are data, where planet is argument 
and sign is value, and lot of planets can be marked as rulers of same sign. 
But this switch don't changes data, where sign is argument, planet is value, 
and here for every sign is only one planet marked as ruler. Graphics 
dispositor chart uses just these data and this chart is undependent of 
switch -YJ.

Here is added new switch -Yr, which allow to change these data and
set as ruler of sign any planet, even Uranian. As result, on graphics 
dispositor chart can be more than 10 fixed planets (originally Mercury and 
Venus rules two signs) but maximum 12, own planet for every sign. 

Using of switch:

-Yr <sign> <object>

Example below changes ruler of Virgo to Proserpina and ruler of Libra to 
Chiron.

-Yr 6 40  -Yr 7 11

This switch changes also data, where planet is argument, that mean, no need 
for additional -YJ <object> <sign> <old_value>. Such change of ruler of sign 
changes also results of planets powers calculations, because changed version 
of Astrolog uses dispositor data in power calculations. 

Using of this switch is probably very rare, so best way is put it to 
astrolog.dat file.


23. Changed default color of Venus from green (Air) to yellow (Earth) because
Venus is always connected with Taurus (Earth), but often as ruler of Libra 
(Air) is used some other planet (for example Chiron). If one likes more 
original color, it can be simply restored by adding of one line to 
astrolog.dat file:

-YJ 4 7 2


Astrolog 5.30b
----------------
Mostly cleanup of code, but also added some new things.

24. In Windows versioon using of parallel-contraparallel aspects can be 
set very simply. But Transit To Transit and Transit To Natal Hits are 
calculated for normal aspects undependent of setting of Parallel aspect 
switch. Only effect is changeing of aspect names from Conjuctions and 
Oppositions to Parallels and Contraparallels, but used are really normal 
aspects, also trines, squares etc. In original Astrolog searching of 
parallel and contraparallel hits is absent at all. Now this omissed 
part is added and is possible to search also Parallel and ContraParallel 
aspects like it was possible with normal aspects.

I don't added any specific switsh to DOS version, in DOS version such 
searches are possible by using of additional switch -ap, which swithes 
to parallel aspects.

Note, that I don't added also any new interpretation.


25. Overwrited temporary decreasing of orbs in case of parallels and 
comparison charts which allowed to remove lot of unnecessary code.


26. Fixed my omission in animation of progressed chart, which itself worked, 
but in cause of transit-transit and transit-natal searches and influences 
caused changes of chart data (in Windows version after repeat of search, 
data of first chart was changed).


27. Fixed original Astrolog omission, where in case of -sr switch 
(equatorial coordinates instead ecliptical) coordinates of house cusps 
aren't transformed from ecliptics to equator, and planets itself was on 
equator, but was placed to ecliptical houses. 


28. All -Z switch (Horizon) charts must be undependent from -sr switch, 
because image of visible sky relatively to local horizon must be 
undependent of coordinate system we use for planets (equatorial, 
ecliptical or some other). In original Astrolog all outputs of -Z switches 
changes in case of additional switch -sr. All routines, connected with 
-Z switch, transforms first coordinates from ecliptic to equator and then 
from equator to local horizon coordinates. In case of -sr switch first 
transform from ecliptic to equator is superfluous, because in case of 
-sr switch coordinates are already given in equatorial system. In 5.30b 
this bug is fixed.


29. Added new switch -Ze, where outputs are relatively to equator instead 
of local horizon. These outputs gives good illustration to parallels-
contraparallels. Combinations -Z0e and -Ze0 are legal, also with -X switch.
In Windows version added respective control in menu "Obscure settings".


30. To graphics outputs with -Z -X switches (overview of space relatively 
to local horizon) are added positions of ecliptics (dark gray dached line) 
and space equator (light gray dached line). Animation of such picture 
gives good possibility to look to moving of planets and important planes 
in time and hepls to understand problems with polar MC and Asc. 

 
31. Fixed my bug with switch -Zd (rising and setting) in polar zone, where 
flipping of MC caused non-existing hits from planets to MC and IC.


32. Fixed bug in calculation of Gauquelin sectors in polar zone. In this 
case some planets can not rise and set during a day. Astrolog restricts 
such planets, but original version don't restores old restriction set 
when returning to standard wheel.


Astrolog 5.30b1
---------------

33. Fixed my own bug, where using SouthNode/Lilith with _b switch (don't use 
ephemeris files) caused in graphics mode error message and exit.


Astrolog 5.30c
--------------

34. Previous bugfix was incorrect. That all was caused by missing of control 
over Proserpina in Windows version and caused lot of problems (in Win version).
This very serious bug is fixed now.


35. Added two points on the sky - Centrum of our Galaxy and Apex of Sun. Here 
are different data, better seems data from "Brockhaus ABC der Astronimie" 
(Leipzig 1961). 
Centrum of Galaxy:
17h 40'       -29 deg
Apex of Sun:
18h 04'       +30 deg

Best data of Centrum of Galaxy gives J. Shklowsky (- 17h 42' 30"
 -29 deg 02',  results of radioastronomy). Of cource, all theses dara are 
transformed to epoch 1900, used by Astrolog.


36. In text mode added support of 8-bit characters in any place (name, place, 
custom interpretation etc.). In graphics mode Astrolog uses his own fonts, and 
needs additional work to create at least codepage 850 support.


37. Added new interpretation way, where interpretation is read from text files,
prepared by user. There are three areas: 
* planets and aspects, where are described meanings of planets in signs and 
houses and their aspects.
* houses, where are described meanings of positions of house cusps, planets 
in houses etc. 
* meanings of stars (if these are unrestricted).
 
NOTE, that interpretation is read from additional text files, which must be 
filled by user. Full description and samples of these additional files are in 
additional files interalt.txt and interalt.zip.

This interpretation is controlled by switches:
-Ia  -  only regrouped info, without interpretation
-Ib  -  full interpretation
-Ip  -  interpretation of planets
-Ih  -  interpretation of houses

All these switches works also without interpretation files.



Astrolog  5.30c1
________________


38. Added 8-bit text support also to graphics mode. Because of structure of 
original Astrolog (uses his own font) here is compiled in support of codepage 
850 (international latin). As I wrote earlyer (look below), in text mode 
actual codepage is supported.


39. Fixed my bug, where some 8-bit characters in first place of  name or 
postion caused damage of text chart header.


Astrolog 5.30c2
---------------

40. Fixed bug in my addition to influence (switch -j0) printout. Total 
aspectation of planets was wrong - was added influence of conjunction of planet
with himself.


41. Aspectation output (switch -j0) is changed. Now are six columns:
Name of planet, sum of harmonical aspects (trines and sextiles), sum of tension
aspects (squares and oppositions), sum of harmonical and tension aspects, where
tension aspects are negative, sum of conjuncions, total aspectation of planet.


42. In "flower" graphics output removed simultaneous influence of opposite 
house cusps - included are conjunctions and trines to unrestricted cusps, but 
removed oppositions and sextiles to allowed opposite cusps. That's similar to 
"smart cusps" option of original Astrolog.


Astrolog 5.30d
--------------

43. Added alternative interpretation of positions of house dispositors in signs 
and houses. Switches -Ib, -Ip, -Ih are same, than in previous versions. 
Changes and additions:

-Ia - added info about positions of situative and natural dispositors in signs 
      and houses
-Id - like -Ih, but added interpretations of positions of dispositors in signs 
      and houses
-Io - All possible interpretations. Like -Ib, but added interpretations of 
      dispositors in signs and houses.

Interpretations of positions of dispositors in houses and signs you can find 
in book "The Astrological Tarot" by Georges Mushery, published in 1994 by 
Senate, an imprint of Studio Editions Ltd, London.
NOTE, that interpretation is read from additional text files, which must be
filled by user. Full description and samples of these additional files are in 
additional files interalt.txt and interalt.zip.


Astrolog 5.30e
--------------

44. Last changes in "alternative interpretation" wasn't reflected in Windows 
version's menus. This omission is fixed.


45. Original Astrolog 5.30 sources (and also older changed versions) can't be 
compiled in text mode without corrections in sources. In version 5.30e it's
fixed. 


46. Changed graphich output "Local Horizon" (switches -X -Z). On ecliptics 
curve (added in version 5.30b) are marked beginnig points of zodiacal signs. 
So finally there are local horizon (horizontal stright), space equator 
(light gray dashed line) and ecliptics (dark gray dashed line). Point 0Ari is 
marked as red, 0Lib as green and all other beginning points of zodiacal sings 
as white points on ecliptics curve.
Animation of this graphics chart is good illustration to problems with Houses 
in polar zone.


Astrolog 5.30f
--------------

47. To graphics wheel and biwheel charts added new feature. Original Astrolog
(and all previous changed versions) shows all exact (or nearly exact) aspects
as solid lines, undependently of real power of aspect. That means, exact
aspect between two very weak planet is solid, and not exact (but much more
powerful) aspect between two important planet is dashed.

Astrolog 5.30f allows to change dashennes of aspect lines relatively to 
calculated POWER, not exactness. That means, solid are all aspects with power
more than 8.0 (default setting), and weak aspects are dached even they are 
exact. New feature is realized in "bonus mode" (-Xi switch or pressing the "i"
key in a window). That allows change between "aspects by exactness" and 
"aspects by power" by the fly. In some cases changes in chart are great, 
in some cases small. To be sure, which mode is in using, to info border just
below "Astrolog 5.30f" in bonus mode are now words "Bonus mode". Originally
in bonus mode are shown only planets without aspects.

One can change minimal aspect power to be solid by new switch -YPp.

-YPp <value>

Default value is 8.0. In Windows version value can be changed in menu
"Obscure settings".


Astrolog 5.30g
--------------

48. To info-border of graphics wheel charts (single and comparison) is
added some info of aspects in (or between) chart(s). There are outputs:

Harm = sum of harmonical aspects (trines and sextiles),
Tens = sum of tension aspects (squares and oppositions),
Summ = sum of harmonical and tension aspects, where tension aspects are negative,
Conj = sum of conjuncions,
Total = total aspectation of planet.

This option is controlled by new switch -XI. If Astrolog is already running
graphichs wheel chart, this option can be toggled on/off by pressing "I".

In case of single chart that's just same info, whish is printed out in
last line in -j0 switch text output. In case of comparison charts there
are summarized aspects between two charts.


49. Fixed omission in aspectation calculations with -j0 switch. There
was always used orb addition, so all numbers was greater (until 7-8%).


Astrolog 5.30g1
---------------

50. Fixed my bug, caused by changes in two previous versions. In case of 
graphichs composite chart graphichs wheel was correct, but planets positions
in infoborder was wrong: there was postitions from first chart, not from 
composite chart. This bug is fixed now.


51. Position of Centrum of Galaxy is corrected. Seems, that I made there 
unnecessary transformation of epoch, which caused difference about 1 degree.
New position for now (26Sag08) better matches other sources than old one
(25Sag22).


Astrolog 5.31g
--------------

52. Alois Treindl modified Astrolog 5.30 and named new version 5.31. It
contains the new Swiss Ephemeris instead of the older Placalc ephemeris.
The responsibility for this modification is with Alois Treindl. Details of
Swiss Ephemeris you can see at http://www.astro.ch/swisseph/ 
Original Astrolog 5.31 with all related files is available at 
ftp://www.astro.com/pub/astrolog/

Instead of older Placalc ephemeris new ones are used: sepl_xx.se1 for planets, 
seas_xx.se1 for astreoids and semo_xx.se1 for Moon. Files with xx=18 covers 
1800 AD - 2400 AD. Windows version has builtin planetary and Moon ephemeris,
which uses another algorithm and covers 3000 BC - 3000 AD. Though, external
ephemeris are more precise and quick. Pkziped set of ephemeris files
sweph_18.zip contains files for 1800 AD - 2400 AD.

Just same modification is made with Astrolog 5.30g1, new version name is 5.31g.
This version hasn't any additional modifications from my side. Windows version
has planetary ephemeris built in to code. 


Astrolog 5.41a
--------------

53. Astrolog 5.40 and then 5.41 with Swiss Ephemeris was released. Here I
moved all my previous changes from Astrolog 5.31g to new original version 5.41.
Because Swiss Ephemeris are more precise and quick than older Placalc
ephemeris, I moved to 5.41 and don't will change versions with Placalc
anymore. So Astrolog 5.40a doesn't exist.


Astrolog 5.41B
--------------

54. Added alternative interpretation of TRANSIT-NATAL comparison charts,
analogious to earlyer interpretation of natal charts. For details see
file interalt.txt. Sample interpretation files with descriptions are in 
file interalt.zip.


55. Added three new switches (YSa, YSj, YSs) for use in astrolog.dat file,
which allows to change some default settings.

   =YSa - sets aspects in listings by default as applying-separating.
   =YSj - influence text chart shows by default also house's influence.
   =YSs - aspect listing shows by default also aspect summary.


56. To most text outputs added headers, where are described type of chart,
in case of comparison charts also data of both charts. In case os multply
charts header is printed only once.


57. To Aspects Configurations list added also "Kite" (described for example in
lesson about aspects by L. M. C. McPherson, file lesson.asp in /astrolog/texts
directory on this server).


58. Fixed original Astrolog bug, appeared between versions 5.30 and 5.40 -
in positions of planets and Houses in Gauquelin graphics chart infoborder 
was wrong.


59. To Windows version "Help" menu added new item - Open World Atlas, which
opens WEB browser and connects to infoserver http://www.astro.ch/atlas/
(I use it often to find coordinates and timezones of different towns).
URL is placed into file watlas.url, added to package.


60. Fixed original Astrolog omission - Windows version "Help" menu looks for
necessary files only in local directory. Now these files are searched through
all directories, connected with astrolog (see helpfile for details of setting
of environment variables) with searching order:

   1) Local directory
   2) Environment directories, set in autoexec.bat, one of them version
      specific (names of directories as examples, names of environment
      variables must be strict and in upper-case:
   a) set ASTR5.41B=C:\aaaaa\541
   b) set ASTROLOG=d:\abbbb
   c) set ASTR=H:\miscfile
3) Default directory, compiled in: C:\ASTROLOG

If Astrolog doesn't find file, it doesn't attempt to start wordpad or
WEB browser but prints only warning, that it can't find file.


61. Improved configuration file astrolog.dat, saved by Windows version - all 
switches of changed versions are in separate section:

; SWITCHES, NOT SUPPORTED BY ORIGINAL ASTROLOG

That simplifies use of the same astrolog.dat file for both changed and original
versions - for original version simply comment out all switches, described
in this section.


62. Fixed bug in stars restriction window, appeared in 5.41a (star Sheat was 
always shown as unrrestricted).


Astrolog 5.41C
--------------

63. Stars calculations moved to Swiss Ephemeris. That improved precision
of calculations. Additional file fixstars.ast is necessary. That's specially 
modified file fixstars.cat from SWEPH, which contains data of about 800 
fixed stars (actually fixstars.ast is last version of fixstars.cat, where
data of stars, used by Astrolog, are copied to first 74 lines). There are 
traditional name of star (like Aldebaran), canonical name (like alTau), 
ephemeris and magnitude. Without this file all stars calculations are 
made as in previous versions. 

64. If fixstars.ast file is used, name and maginitude from file overwrites 
these internal data of Astrolog and are printed out in listings etc. In some
printouts are used also canonical names of stars.

65. Stars are searched by line (star) number in fixstars.ast file, so copying 
of lines in astrolog.ast to first 74 positions gives possibilty to use 
ALL stars from this catalogue (in blocks by 74 stars, allowed by changed
Astrolog). 

Note, that most stars in catalogue hasn't traditional name but only
canonical name. If you want to use such a stars, I suggest to write 
canonical name also into traditional name field (like i'ts made with 
zeRet in fixstars.ast). In other case you will see blank starname(s) 
in all listings and if such stars are more than one, it's difficult to 
distinguish them (in some printouts they can be distinguished by 
canonical name).

66. Changed stars restrictions menu in Windows version. Internal names of
stars, used by Astrolog, are overwritten by names from fixstars.ast file.
Canonical names aren't used there, so if you will use stars with blank
traditional name filed, it will be blank also in menu.

Note, that when Astrolog starts first time with disallowed fixed stars,
internal stars names are used (because fixstars.ast file isn't used in 
this case). If you use modified fixstars.ast file, you have to cast once 
any chart with all fixed stars unrestricted. Then all stars names will be 
overwritten and with next charts you can see there new names from 
fixstars.ast and use them for restriction. 

In case of alternative stars restriciton you don't need stars restriction
menu, stars are restricted and unrestricted automagically. But after first
chart with fixed stars there will be names from fixstars.ast.

67. Changed some text outputs: 
In chart listing object name field is increased to 10 characters, (important 
for stars!), for stars added canonical names instead of blank field for 
velocity. 
In Local Horizon and Prime Vertical text charts added recpective line to 
header, object names increased to 7 characters.

68. Stars colours can be customized. New switches:

-YUb1 <value> for stars with magnitude below 1.0
-YUb2 <value> for stars with magnitude between 1.0 and 2.0
-YUb3 <value> for stars with magnitude over 2.0

Colors:

0 - black, 1 - maroon, 2 - dk. green, 3 - orange, 
4 - dk. blue, 5 - purple, 6 - dk. cyan, 7 - lt. gray, 
8 - dk. gray, 9 - red, 10 - green, 11 - yellow, 
12 - blue, 13 - magenta, 14 - cyan, 15 - white.

"Save settings" in Windows version saves also these stars colours settings.

69. To Windows version "Help" menu added new item - Open Fixed Stars, which
opens WEB browser and connects to infoserver http://www.winshop.com.au/annew/
URL is placed into file stars.url, added to package.
