Hi everybody,
Thanks for your responses.
I am Java programmer and I don't know how to invoke the C routine inside a service program.
Do you think one can warp the C program with CL program, so I can call the CL program instead of the C program?
(The C program is used by other applications, so I can't make any change on it).
Regards,
Tomer S.

Isn't argv is an array of pointers ... so they are, by definition, bidirectional ... if you pass in pointer parameter ... and change the contents of that memory ... the values are changed.
And, I think, PCML passes everything by reference.
Hmm ... maybe it would be better to invoke the C routine inside a service program ... so that the QZRUCLSP api will be used?
Back in the day at SSA we had to create our own parameter passing
technique. It used a stream file to pass parameters between the two
programs.
I don't think the same remote program invocation mechanism existed back then.
Ugh. The flashbacks! THE FLASHBACKS!!!!!
Aaarrrgggg! PSSD! Post SSA Stress Disorder ... I suffer from it too.
