RE: CL Parameters sharing memory?

Thanks Carel & Buck.

I did know about the 15p5, but I guess the 32a limitation (wow, talk about small) always flew by me.

I do have a command front end, which is probably why the command works for calling the CL, but that CL then subsequently submits another, and therein lies the problem. Thanks for the help.

Kurt,

Default lengths of parameters passed on a call are 15P5 for numeric
(packed, 15 with 5 decimals) and 32 for character parameters.

Different lengths of a character parameter requires a command front end to
avoid this problem.

An alternative is to pass it as a parameter one character longer than the
receiving pgm and have the last position filled with a character.

So to pass parameter &CNAME dfine it in pgm A as 46 and give it the value
"kurt test
x" (these are 46 characters.)

The receiving pgm B has the parameter defined as 45.

With regards,
Carel Tejgeler

I'm on v5r4.

I have a CL that submits a CL, and it appears two of the parameters are

sharing a location in memory. Is there a limitation on the size of a

field that can be submitted to a CL? I tried searching online but wasn't

finding anything. I can get around this situation by putting the big

parameter last, but I wanted to understand why this is happening.

So when I pass a 45a and a 1a variable, the 45a variable contains both

values:

&CNAME = kurt test N

Here's my source:

TESTCL1
PGM
DCL VAR(&CNAME) TYPE(*CHAR) LEN(45) Value('kurt

test')

DCL VAR(&V51) TYPE(*CHAR) LEN(1) Value('N')

SBMJOB CMD(CALL PGM(TESTCL2) PARM(&CNAME &V51))
ENDPGM

TESTCL2
PGM PARM(&CNAME &V51)
DCL VAR(&CNAME) TYPE(*CHAR) LEN(45)
DCL VAR(&V51) TYPE(*CHAR) LEN(1)

SNDMSG MSG('&V51 = ' *CAT &V51) TOUSR(KURT)
SNDMSG MSG('&CNAME = ' *CAT &CNAME) TOUSR(KURT)
ENDPGM
