GASS Operations
Thanks you very much for using MSI.
OPERATION 250 - SET TIME-OUT
OPERATION 0 (OR 123) WILL WAIT FOR DATA UNTIL A FIELD DELIMITER (CARRIAGE
RETURN) FOREVER UNLESS IT IS MODIFIED BY OPERATION 250 IN SOME PREVIOUS
I-FORMAT FIELD CONTAINING THE NUMBER OF SECONDS TO WAIT BEFORE TIMING-OUT. IF
THE DELIMITER IS NOT RECEIVED BEFORE THE TIME-OUT, INPUT WILL BE TERMINATED
AND OP.251 MAY BE USED TO TEST THE STATUS OF THE TIME-OUT. THIS OPERATION WAS
WRITTEN FOR A SPECIFIC INTERFACING PROBLEM, BUT MAY BE USED FOR SECURITY
PURPOSES, ETC.
SEE OPERATION 251 FOR AN EXAMPLE OF THE USE OF THESE TWO OPERATIONS.
A-250
OPERATION 251 - TEST TIME-OUT
OPERATION 251 IS USED TO PLACE THE RESULT OF THE LAST INPUT OP.0,
MODIFIED BY OP.250. IF THE OP.0 TIMED-OUT, THE OP.33 FLAG IS SET TO 1, AND IF
IT DIDN'T TIME-OUT, THE FLAG IS SET TO 0, WHEN OP.251 IS PROCESSED. THIS IS
USED TO SEE IF THE DATA RECEIVED BY THE OP.0 FIELD MAY BE VALID. IF THE FIELD
TIMED-OUT, THEN NO OR PARTIAL DATA WAS RECEIVED.
EXAMPLE:
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | I6 | | | 40 Y 18(10) Y 250 N
2 | A78 | ENTER A78 DATA | | 0 Y 103 N
3 | I6 | | | 251 Y 143(0,5) N
4 | A1 | YOU TIMED OUT! | | 55 N
5 | A78 | | | 62 Y 104 N
IN THE EXAMPLE ABOVE, FIELD 1 SETS A TIME-OUT LENGTH OF 10 SECONDS FOR
THE OP.0 IN FIELD 2. FIELD 3 TESTS THE RESULT OF THE TIME-OUT AND SKIPS THE
MESSAGE IN FIELD 4 IF A TIME-OUT DID NOT OCCUR. FIELD 5 THEN VIEWS ANY DATA
OBTAINED AND STORED IN MEMORY BY FIELD 2.
A-251
.PA
OPERATION 252 - PLACE OUTPUT DEVICE PR # IN THIS I-FIELD
OPERATION 252 PUTS THE CURRENT OUTPUT DEVICE PR NUMBER FOR THE CURRENT
DEVICE INTO THE CURRENT I-FIELD. IT MUST BE IN AN I-FIELD AND IF PRECEEDED BY
OPERATION 62 WILL FLASH THE PR NUMBER.
EXAMPLE:
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | A1 | YOUR CURRENT PR DEVICE IS | | 196 Y 55 N
2 | I4 | | ^| 62 Y 252 N
THE EXAMPLE REPORT WILL FLASH "YOUR CURRENT PR DEVICE IS 4" (IF IT IS
4) AND PLACE THAT NUMBER AS DATA IN FIELD 2. THIS IS NOT THE SAME AS
OPERATION 173.
A-252
.PA
OPERATION 253 - PUT UNIT NUMBER IN THIS I-FIELD
WHEN USING OPERATION 111, IT IS SOMETIMES USEFUL TO SAVE THE CURRENT UNIT
NUMBER IN ORDER TO RESTORE IT LATER. ALSO TO WRITE CODE THAT RELATIVELY
ADDRESSES UNITS IS SOMETIMES REQUIRED. OPERATION 253 DOES THIS BY BRINGING THE
UNIT INTO THE CURRENT I-FIELD.
EXAMPLE:
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | I6 | | | 40 Y 253 N
2 | I6 | | | 18(2) Y 111 N
3 | A72 | | | 116(1,3) Y 62 Y 102 N
4 | I6 | | | 10(1,150) Y 111 Y 103 N
5 | A1 | YOU ARE IN UNIT | | 196 Y 55 N
6 | I6 | | | 62 Y 104 N
THE EXAMPLE SAVES THE CURRENT UNIT NUMBER IN FIELD 1, THEN CROSSES TO
UNIT 2 (SAME FILE) AND VIEWS WHAT IS IN ROW 3 OF TABLE 1 THERE. IT THEN
RESTORES THE PROGRAM TO THE ORIGINAL UNIT (FIELD 4) AND FLASHES THE UNIT
NUMBER.
A-253
.PA
OPERATION 254 - MOVE CURRENT FILE NUMBER INTO THIS I-FIELD
WHEN USING OPERATION 112, IT IS SOMETIMES USEFUL TO SAVE THE CURRENT FILE
NUMBER IN ORDER TO RESTORE IT LATER. ALSO TO WRITE CODE THAT RELATIVELY
ADDRESSES FILES IS SOMETIMES REQUIRED. OPERATION 253 DOES THIS BY BRINGING THE
FILE NUMBER INTO THE CURRENT I-FIELD.
EXAMPLE:
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | I6 | | | 40 Y 254 N
2 | I6 | | | 18(2) Y 112 N
3 | A72 | | | 116(1,3) Y 62 Y 102 N
4 | I6 | | | 10(1,150) Y 112 Y 103 N
5 | A1 | YOU ARE IN FILE | | 196 Y 55 N
6 | I6 | | | 62 Y 104 N
THE EXAMPLE SAVES THE CURRENT FILE NUMBER IN FIELD 1, THEN CROSSES TO
FILE 2 (SAME UNIT) AND VIEWS WHAT IS IN ROW 3 OF TABLE 1 THERE. IT THEN
RESTORES THE PROGRAM TO THE ORIGINAL FILE (FIELD 4) AND FLASHES THE FILE
NUMBER.

OPERATION 255 - NO OPERATION
OPERATION 255 MAY BE USED ANYWHERE IN ANY OPERATION FIELD. IT DOES
NOTHING.
A-255
.PA
OPERATION 256 - PUT MEMORY IN I/O BUFFER
OPERATION 256 WAS WRITTEN TO ALLOW SUBROUTINES CALLED WITH OP.35 TO
RETURN DATA FROM A LOWER LEVEL. BEFORE OP.256, ALL RETURNS OF DATA FROM A
LOWER LEVEL REQUIRED THE USE OF SOME GLOBAL SYSTEM RESOURCE, SUCH AS TABLES OR
SYSTEM MEMORY. THIS CREATED A PROBLEM IN WRITING MULTI-USER SYSTEMS, BECAUSE
PROTECTION SCHEMES HAD TO BE DEVISED BY THE PROGRAMMER.
OPERATION 256 PLACES THE FIRST 134 BYTES OF MEMORY INTO THE I/O BUFFER
FOR THE DEVICE. THIS BUFFER IS NOT MODIFIED ON RETURN FROM A LOWER LEVEL, AND
MAY BE RETREIVED BY THE USE OF OPERATION 257.
EXAMPLE: 256
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | I6 | GET VALUE FROM ABOVE | | 40 Y 104 N
2 | I6 | ADD 64 FOR TRANSLATION | | 18(64) Y 10(1,2) Y 103
Y 256 N
THE ABOVE EXAMPLE RUNS AT THE LOWER LEVEL TO TRANSLATE THE I-VALUES
PASSED TO IT IN MEMORY TO LETTERS OF THE ALPHABET BY ADDING 64. THE RESULTS
ARE PLACED IN THE I/O BUFFER FOR RETURN BY THE LAST OPERATION IN THE REPORT.
SEE THE NEXT PAGE FOR DETAILS OF THE CALLING REPORT.
A-256
.PA
OPERATION 257 - PUT I/O BUFFER IN MEMORY
OPERATION 257 IS THE COMPLEMENT OF OPERATION 256, IN THAT IT GETS THE
DATA FROM THE DEVICE'S I/O BUFFER AND PLACES IT IN THE CURRENT LEVEL'S MEMORY.
THIS EFFECTIVELY DEFEATS THE RESTORATION OF MEMORY ON RETURN, AT LEAST FOR THE
FIRST 134 BYTES.
EXAMPLE: 257
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | I6 | FOR INCREMENT | | 40 Y 18(1) N
2 | I6 | LIMIT | | 18(10) N
3 | I6 | COUNT & PASS TO TRANSLATOR | | 10(1,3) Y 103 Y 89 Y
35(6,256) N
4 | A1 | VIEW MEMORY AFTER | | 257 Y 62 Y 104 N
5 | I6 | LOOP TEST | | 12(2,3)Y 33 Y 143(4,3)N
THE EXAMPLE GIVEN WORKS WITH THE PRECEEDING EXAMPLE TO IMPLEMENT A
TRIVIAL CHARACTER-TRANSLATION SUBROUTINE. I-VALUES FROM 1 TO 10 ARE GENERATED
BY "257" AND PASSED TO "256", WHICH ADDS 64 TO THE VALUE AND PASSES THE ANSWER
BACK USING THE I/O BUFFER. FIELD 4 OF "257" VIEWS ITS MEMORY AFTER OPERATION
257 IS PROCESSED, TO SHOW THE VALUE RETURNED BY IT.
A-257
.PA
OPERATION 258 - VIEW D-DATA WITH COMMAS, A AS HEX
OPERATION 258 WORKS LIKE OPERATION 62 TO VIEW DATA ENTERING A FIELD, BUT
IN ADDITION IT CAUSES COMMAS TO BE INSERTED INTO THE STRING REPRESENTATION OF
THE NUMBER BEFORE IT IS VIEWED. THIS IS USED FOR GEN-SIDE REPORTS WHICH DEAL
WITH NUMERICAL (PRIMARILY DOLLAR) VALUES. THE USER IS CAUTIONED TO USE FORMAT
WIDTHS WHICH ALLOW ROOM FOR THE COMMAS, OR ELSE THE LEADING (MOST SIGNIFICANT)
DIGITS OF THE STRING MAY BE LOST DUE TO TRUNCATION.
IN AN A-TYPE FIELD, OPERATION 258 VIEWS THE FIELD AS ITS HEXIDECIMAL
EQUIVALENT.
EXAMPLE: 258
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | D10.2 | GET VALUE FROM TABLE | | 40 Y 116(9,2) Y 94 N
2 | D12.2 | MULTIPLY BY CONSTANT | | 19(50.00) Y 15(1,2) Y
AND PUT IN MEMORY | | 103 N
3 | D16.2 | VIEW DATA WITH COMMAS | | 258 Y 104 N
IN THE EXAMPLE, FIELD 1 GETS A VALUE FROM A TABLE, WHICH IS MULTIPLIED BY
50 IN FIELD 2. THE RESULT IS PLACED IN MEMORY, TO BE VIEWED BACK WITH COMMAS
INSERTED BY FIELD 3.
A-258
.PA
OPERATION 259 - VIEW MEMORY TO OP 83 DATA POSITION
OPERATION 258 IS FORMAT INDEPENDENT AND VIEWS WHAT IS IN MEMORY FROM DATA
POINT 1 TO THE DATA POINT CONTAINED BY THE OPERATION 83 REGISTER.
EXAMPLE:
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | A78 | DATA TO MEMORY | | 0 Y 103 N
2 | I6 | NUMBER TO VIEW | | 0 Y 83 Y 259 N
WHEN THE DATA IS ENTERED INTO FIELD 1, IT IS PLACED IN MEMORY FROM D.P.1
TO D.P.78. FIELD 2 WILL PUT THE # I/P INTO THE 83-REGISTER AND VIEW THAT
NUMBER OF CHARACTERS FROM MEMORY.
A-259
.PA
OPERATION 260 - PUT THE NUMBER OF BYTES I/P INTO FIXED PT REG
THERE ARE OCCASIONS WHEN THERE IS A NEED TO KNOW HOW MANY CHARACTERS HAVE
BEEN READ-IN USING OPERATION 0 OR 123. ON COMPUTER TO COMPUTER LINKS, A FIELD
MAY BE FORMATTED AS AN A134 AND WE MUST KNOW THE NUMBER OF CHARACTERS THAT
HAVE BEEN READ IN PRIOR TO THE CARRIAGE RETURN (OR SOME DELIMITER) IN ORDER TO
PEFORM A PARTICULAR PROCESS. WE USE OPERATION 260 AFTER THE I/P OPERATION TO
RETRIEVE THIS VALUE.
EXAMPLE:
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | A134 | ENTER UP TO 134 CHARACTERS | | 0 N
2 | I6 | CHARCTERS WERE READ | | 260 Y 103 Y 196 Y 62 Y
| | | | 104 Y 55 N
IN THE EXAMPLE, WHEN A STRING IS ENTERED, THE NUMBER OF CHARACTERS THAT IS
INPUT WILL APPEAR FOLLOWED BY "CHARACTERS WERE READ."
OPERATION 260 WORKS WITH ALL FORMATS.

OPERATION 261 - DISABLE TABLE ERROR MESSAGES
UNDER NORMAL CIRCUMSTANCES, THE SYSTEM WILL GIVE A WARNING MESSAGE IF IT
IS UNABLE TO ACCESS A TABLE DURING PROCESSING. THIS HAS CAUSED PROBLEMS TO
SOME OLDER APPLICATIONS, SO OPERATION 261 HAS BEEN ADDED TO DISABLE THESE
ERROR MESSAGES SHOULD THAT BE REQUIRED. IT MAY BE PLACED IN ANY FIELD.
OPSRT - 10/16/89
A-261
.PA
OPERATION 262 - RE-ENABLE TABLE ERROR MESSAGES
IF TABLE ERROR MESSAGES HAVE BEEN DISABLED BY THE USE OF O.261, THEY MAY
BE RE-ENABLED BY OPERATION 262, WHICH MAY BE PLACED IN ANY FIELD.
OPSRT - 10/16/89
A-262
.PA
OPERATION 263 - VIEW DATA IN THIS FIELD WITH FORMS CONTROL
OPERATION 263 CAUSES THE DATA IN THE FIELD TO BE VIEWED AT GEN-TIME,
ACCORDING TO THE FORMAT OF THE FIELD AND THE ^ OR \ FORMS CONTROL CHARACTER.
THIS MAY BE USED IN ANY FORMAT FIELD, AND IN NUMBER FIELDS WILL VIEW THE
CONTENTS OF THE FIELD'S FIXED OR FLOATING-POINT REGISTER, AS APPROPRIATE.
EXAMPLE: 263
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | A134 | ENTER UP TO 134 CHARACTERS | | 0 N
2 | I6 | CHARCTERS WERE READ | | 260 Y 263 Y 55 N
THE ABOVE EXAMPLE IS A MODIFICATION OF THE EXAMPLE FOR OPERATION 260,
WHICH MAY BE REFERRED TO FOR COMPARISON. THE TWO EXAMPLES DO EXACTLY THE SAME
THING WHEN PROCESSED. NOTE THAT FOUR OPERATIONS HAVE BEEN REPLACED WITH ONE.
THIS SPEEDS PROCESSING, AND MAKES THE PROGRAMMER'S JOB EASIER.
OP183 - 10/16/89

OPERATION 264 - REPLACE SPACES IN THIS FIELD WITH LAST I-VALUE
OPERATION 264 MUST BE IN AN A-FIELD AND SEARCHES THE FIELD FOR SPACES
AND RPLACES THEM WITH THE INTEGER PROCESSED IN THE LAST I-FIELD.
EXAMPLE: 264
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | I6 | ENTER THE REPACEMENT CHAR | ^| 196 Y 0 N
2 | A78 | ENTER UP TO 134 CHARACTERS | ^| 0 Y 264 Y 103 N
3 | A78 | | ^| 62 Y 104 N
THE EXAMPLE REQUIRES AN INTEGER TO BE ENTERED INTO FIELD 1 AND AN
ASCII STRING TO BE INPUT INTO FIELD 2 WHERE THAT STRING HAS ALL SPACES CHANGED
TO THE CHARACTER REPRESENTED BY THE DECIMAL VALUE INTERED INTO FIELD 1. FIELD
3 BRINGS THE EDITED STRING IN FROM MEMORY AND FLASHED IT.

OPERATION 265 - UPDATE GASS DATE/TIME FROM MEMORY
OPERATION 265 WILL TAKE THE FIRST 14 DATA POSITIONS OF MEMORY TO UPDATE
THE GASS DATE/TIME. MEMORY MUST BE SET UP AS FOLLOWS:
11111 (DATA
12345678901234 POSITIONS)
MM-DD-YY HH:MM (IMPORTANT NOTE: HH MUST BE 24 HOUR TIME)
THIS CONFORMS TO MEMORY SET UP BY OPERATION 226 WHEN MEMORY WILL
CONTAIN THE DOS DATE/TIME.

OPERATION 266 - TAKE VALUE IN THIS I-FIELD TO CHANGE SPACE TO CR
OPERATION 266 USES THE VALUE IN THE CURRENT I-FIELD AS THE UPPER LIMIT
OF THE NUMBER OF CHARACTERS TO ALLOW TO BE INPUT BEFORE A SPACE IS CHANGED TO
A CARRIAGE RETURN. THIS ALLOWS FOR A POSSIBLE WORD WRAP CAPIBILTY USING
OPERATION 0.
IF A NEGATIVE VALUE IS PARAMETRIC TO OPERATION 266, THEN ON
INPUT INTO SUBSEQUENT FIELDS,THE DATA WILL BE RETURNED WHEN THE SPECIFIED
ABSOLUTE NUMBER OF CHARACTERS HAVE BEEN ENTERED.
EXAMPLE: 266
FIELD | FORMAT | COMMENTS |\^| OPERATIONS
------|--------|----------------------------------|--|------------------------
1 | I2 | |^ | 18(60) Y 266 N
2 | A78 | ENTER 78 CHARACTERS OF DATA |^ | 0 Y 267 N
3 | I2 | |^ | 18(-1) Y 266 N
4 | I1 | ENTER 1 INTEGER; NO ENTER KEY! |^ | 0 Y 267 N
THIS EXAMPLE WILL ALLOW NORMAL INPUT INTO FIELD 2 EXCEPT AFTER 60
CHARCTERS HAVE BEEN INPUT, A SPACE OR CR WILL BE TAKEN AS A CR.
IN FIELD 3, THE NEGATIVE VALUE OF 266 WILL CAUSE ONLY 1 CHARACTER
TO BE INPUT INTO FIELD 4 WHEREUPON DATA WILL BE RETURNED AUTOMATICALLY.

OPERATION 268 - ALLOW DEVICE MEMORY TO BE NON DESTRUCTIVE ON CALLS
OPERATIONS SUCH AS 35, WHICH IS A SUBROUTINE CALL, RECEIVES DEVICE
MEMORY (THAT WAS SET UP BY SOME OPERATION SUCH AS 103 OR 105) AS IT WAS IN THE
CALLING REPORT. HOWEVER WHEN THE RETURN TO THE CALLING REPORT IS MADE, MEMORY
IS STILL THE SAME AS BEFORE THE CALL. OPERATION 268 REVERSES THIS SITUATION AND
ALLOWS DEVICE MEMORY TO BE GLOBAL TO THE DEVICE ON RETURNS FROM CALLS SUCH AS
OPERATIONS 35, 37,52,120 AND 121.
EXAMPLE: 268

OPERATION 271 - MAP TABLES TO ANOTHER FILE
OPERATION 271 MAPS SETS OF TABLES FROM ONE FILE TO ANOTHER FILE.
AFTER A MAPPING HAS BEEN ESTABLISHED, A REFERENCE TO ANY TABLE WITHIN A SET
WILL REFERENCE THE SAME TABLE IN THE TARGET UNIT AND FILE; TABLES WITHIN
THE SOURCE FILE WILL BE LOST. THE MAPPING WILL BE LOST WHEN THE SYSTEM IS
LOADED AND THE TABLES IN THE SOURCE FILE WILL BE REBORN. OPERATION 271
USES THE FOLLOWING REGISTERS:
OPERATION 38 REGISTER - TARGET UNIT
OPERATION 51 REGISTER - TARGET FILE
OPERATION 81 REGISTER - BEGINNING TABLE NUMBER
OPERATION 83 REGISTER - ENDING TABLE NUMBER
* THE CURRENT UNIT AND FILE WILL BE THE SOURCE FILE *
* THERE MAY BE 32 SETS OF MAPPINGS PER SYSTEM LOAD *
