Re: 3000-char CL parm padded with hex zeros

Thanks Buck! Gotta remember the wiki! Now bookmarked.

How is it that, after 20+ years on the platform, I don't recall running
into this specific issue (parms defined identically in both the caller and
callee)? I typically don't create commands that are not used
interactively, and I'm certain I've passed large parameters like this
before.

So, I guess I'm writing a command for this one.

CL program PGMA submits CL program PGMB, passing three parameters: A10,

Before the SBMJOB CMD(CALL PGMB PARM(A10, B10, C3000), I have a DMPCLPGM
that shows that C3000, at the end of the content PGMA puts in it, is

padded

with blanks (x'40'). However, upon entry into PGMB, the padded blanks
convert to hex zeros (x'00'), and this creates a problem when I use the
%trim built-in. I.e., nothing gets trimmed.

Is this the expected behavior?

Yes.

I vaguely recall issues where garbage shows
up in parameters when passing a literal that is shorter than the

receiving

parameter, but in this case, both programs have the same variable
definitions for the three parameters.

Actually, there are three programs involved:
PGMA
QCMD
PGMB

Where is the definition of the three parameters for QCMD?
