It's been quite a long while since I had a finger in any PL1 code, but I now
have a small PL1 side project I need some help with.
I have a question about how to handle not only the "standard" EXEC PARM of up
to 100 bytes, but also how to handle the newer EXEC PARMDD option which allows
up to 32760 bytes of PARM data in a PL1 OPTIONS(MAIN) procedure.
In COBOL the quasi-standard I have been using is this structure in the LINKAGE
section of a main program that expects PARM/PARMDD input:
LINKAGE SECTION.
01 PARM-AREA.
05 PARM-LEN PIC S9(4) BINARY.
05 PARM-DATA.
10 PARM-X OCCURS 0 TO 32760
DEPENDING ON PARM-LEN
PIC X.
That structure occupies no storage in the COBOL program, and instead is
accessed directly by using the R1 address passed to the COBOL program by the
"EXEC PGM=" process.
How do I define a similar vehicle for PARM data in current releases of
Enterprise PL1 (I have the V5.3.0 version available to me for this project)?
Is there a way to do it with a CHAR (*) VARYING BASED variable? Or have I lost
all sense of what is and is not possible in PL1?
Please be gentle, it has been a very *long* time since I have done any actual
PL1 coding, and a lot of memory cells from that bygone era have been lost to
bit rot.
Any RTFM's or url pointers much appreciated.
Peter
