RE: Parm identification routine...

Don,

I'm not sure this information would be available. Where you can get parm
count from a program is shows in the DSPPGM screen. Beyond that all you are
really passing is pointers so I'm not sure you can get the info. 

If I write an RPG program and declare 5 parameters but I only pass 3 the
program will work fine as long as I don't access those last 2 parms. Also,
if I write a program that takes a char(5) and pass it a char(9) it will work
fine too. It will even work if I pass the program a char(4) -- granted, it
will munge one byte of memory somewhere. I can even pass a character field
into this numeric parameter.

My point is that the checking doesn't occur until the system actually tries
to use the memory passed to it. This could be hundreds to thousands of lines
into the program, and it may even be in another program -- program 'A' takes
a dec(5,0) and passes it to program 'B', program 'B' will blow up if you
pass character data, not program 'A'.

Therefore I submit that this information is not available via "object
interrogation"

Greetings,

You've seen it before, you'll see it again...someone loses control of the
number, variable type, positioning, etc., of a parm list and is major
league SOL, up the creek, and in deep kemchi...

Now, my gutt tells me that this info is available by object interigation
and that it doesn't matter (other than perhaps differing methods) as to
observability....as runtime would have this info, regardless...

Has anyone written such a utility yet?
