HELLO WORLD AGAIN!!

     I wrote this application after I had discovered many of the
graphics routines in the AVIGO. I proceed to draw a dialog box by
"scratch" so to speak, with the routines I found. I hope it somewhat
resembles the dialog boxes from the real system calls. I still haven't
found routines to put up dialog boxes... So far, these are among the
routines I have found...

       CALL    $0099           	;INVERT a square field of pixels
       CALL    $00AB           	;DRAW DOTTED SQUARE
       CALL    $00AE           	;DRAW DOTTED FILLED (CHECKERBOARD) SQUARE
       CALL    $00B1           	;DRAW LINE FROM X1,Y1 TO X2,Y2
       CALL    $00B7   		;Draw a circle from ceter to radius
       CALL    $00E1   		;Draw a filled circle from center to radius
       CALL    $00BD           	;Sets security lock to the unit
       CALL    $0021  		;Turn on/off the backlight (LD A,$00 or $01)
       CALL    $002D  		;Go into POWER DOWN mode
       CALL    $0041       	;SET TIME ???
       CALL    $0044       	;SET DATE ???

These are only a sample really - check out the asm file for ALL the routines

     I hope other programmers will use this utility to try to discover
some of the other System Routines in the AVIGO. In just the past few
weeks I've discovered quite a bit, with a little help I know we can
begin to develop third party software for this device! Contact me if
you want to find out more...
