RE: Parameter lengths and calling from command line

Maybe that's good for most questions here, and I've had situations, plenty enough, when I just needed the simple answer like right now.

But for what it's worth, folks, in general, I'm one who really appreciates "under-the-covers" explanations of what's going on. :)

When I'll find time to have a crack at fixing it is another matter Buck - but it does seem to me that the wiki entry is wayyyyy over complicated. Certainly in its opening section. All the stuff on the PASA is overkill to my mind and would tend to confuse anybody who actually needs the answer.

But maybe it's just me.

Back to the Future -- CL 101!!

This is all described in something like chapter 9 of the CL
Programming manual. It includes the several alternatives that others have given here.

With the advent of internet / HTML based manuals, I find it really
difficult to give a canonical reference.

which is
Programming > Control language > CL programming > Controlling flow and
communicating between programs and procedures > Passing parameters

It seems to me that this is THE most frequently asked question about
programming. We had a FAQ page on it when we had a Midrange FAQ
(thanks
David!) and we have a wiki page on it now (Thanks David!)
http://wiki.midrange.com/index.php/Parameter_passing

If there are some words that can be put in the wiki that would help
people understand what is happening, I would love to add them. In
essence, this is a buffer overflow situation: the callee is reading
more memory than the caller allocated.

Thanks all... I guess I HAD been in the habit of building commands
to run the program but I certainly had forgotten that....

You folks also gave me some other approaches which I may check out,
but wrapping it with a command was the easiest and it works great.

I always do it with a command.
