Hello,

You need to consider this as much stronger than a suggeston.
If you refuse to use standard linkage for every assembler module you will cause yourself (and probably others) a great amount of trouble. . . |

So, the final edition should be like below:
| Code: |
BEGIN CSECT
SAVE (14,12)
BALR R3,0
USING *,R3
LA R15,REGSAVE POINT TO OUR SAVEAREA
XC 0(REGSAVEL,R15),0(R15) ENSURE X'00'S
ST R13,4(,R15) BACKWARD-CHAIN
ST R15,8(,R13) FORWARD-CHAIN
LR R13,R15 POINT TO OUR SAVEAREA
OPEN (TEACHERS,(INPUT)) OPEN INPUT FILE
LTR R15,R15
BNZ RTN2CLLR
LOOP GET TEACHERS,IREC READ A SINGLE TEACHER RECORD
B LOOP REPEAT
ATEND CLOSE TEACHERS
L R13,4(,R13) RESTORE CALLERS R13
RTN2CLLR RETURN (14,12),RC=(15)
DS 0F ENSURE ALIGNMENT
REGSAVE EQU * REGISTER-SAVEAREA
DS 18F 18-WORDS
REGSAVEL EQU *-REGSAVE RSA OVERALL-LGTH
TEACHERS DCB LRECL=L'IREC,DSORG=PS,RECFM=FB,MACRF=(GM),
DDNAME=TEACHER,
EODAD=ATEND
LTORG
YREGS
IREC DS CL80
BEGIN AMODE 24
BEGIN RMODE 24
END |

I wouldn't use R15 when setting up SAVEAREA and your RTN2CLLR label should be on the L R13,4(R13) statement.

Garry,
At this point in the program, R15 is considered a work-register (it's prior to the OPEN) and so, it can be used as such.

Bill,
Accepted, but I would still prefer to avoid using R15.

Yes, correct...
