You found the solution, fine. Fyi, I recently wrote a assembler subroutine, it
can be called from COBOL, C, PL/I and probably other, to access REXX variables
and the TSO stack, and it can also start a REXX. It is available on request.
Thanks Bernd,
yes I did wonder about that, I will fix it.

Found it, it was down to C pointers as expected / feared.
This works, note the use of 'textlenp' in the call:
#pragma linkage (rxhlicpl, OS)
main () {
extern int rxhlicpl();
Thanks Tony,
yes I am at the 'I just want it to work stage'.
I do actually have a "#pragma linkage(rxhlicpl,OS)" statement in there, should
have listed that as well.

Most SMF records can be copied to a normal VB dataset. As I recall, only one or
two CICS records were really that big (or perhaps it is DB2, it's been a
while)? Anyway, you can select the record types that you need and the use SORT
to convert to normal VB.
Turns out the problem is with IRXSAY, I can read and write variables using
IRXEXCOM. But IRXSAY returns with return code 28 'A language processor
environment could not be located'. Unfortunately I was not checking for IRXSAY
return codes, as IRXSAY just works, well at least in TSO it does. So
"PROF NOPREFIX works but can leave you that setting when you don't want it on
termination."
Do check if it is already off before you change it, and if so dont set it on
afterwards. Also remember that the prefix is not neccessarily the user id, so
you need something like the following to
"INRTDDN, which is valid for INFO but not for ALLOC"
For alloc you must use the RTDSN(varname) parameter. But a good point, it
really should have been the same.

It will work, that is how I usually do it.
And so will this:
"line_after .zl = 'this is a new line'"
"line_after .zl = ' and so is this '"
Though I prefer to assigh the value to a variable and then use that, mostly
because it is easier to handle quotes and complex strings that way.
Since you are running a REXX anyway, that REXX could copy DDname SYSIN to a
temporary dataset, which is then used for SYSIN in the 2nd step, A simple REPRO
INFILE(SYSIN) OUTFILE(TEMP) should do it.

If it is a short template then you can insert the lines from the macro. Replace
the COPY command with
/* Insert template */
s='Template line 1'
"line_after .zl = (s)"
s='Template line 2'
"line_after .zl = (s)"
and so on and so forth
I think this is the shortest sample I can come up with. It generates first or
next membername for the day, then edits that member using itself as edit macro.
The edit macro part copies the template and saves the member. Remove the
'CANCEL' command to stay in edit.
The command can be executed
