RE: Long parameter issue

Thanks a lot, Tom; I've already created a *CMD object and it worked...

I try to pass a char parameter of 100 to an RPG program. The problem

order to use only what I need it), I cannot do it because of that...

Florin:

When you pass the value, are you passing all 100 characters
including trailing blanks? For example, if you issue the CALL from a
command line, are you putting the parameter value in quotes with the
trailing quote far enough out to include all necessary blanks?

If you don't, then whatever is in memory is what will get picked up
by your RPG program. You have to put blanks into the memory in some way.

One way to do that is to define a *CMD object over the RPG program
that declares the parameter to be 100 characters long.

If you're going to call the RPG program from a CL program, then the
CL program is responsible for making sure that the memory is correct
out to 100 characters. If the CL program receives the value in its
parameter list, then whatever calls the CL is responsible for the
memory being correct.
