Re: Examine Parms in a Loop

[Booth Martin <booth@xxxxxxxxxxxx>]

One possible solution, if you are also working with the calling program, 
is to pass a single data structure so that there is, in fact, only one 
parm (or none).

Then you have a variety of choices as to how to do your checking against 
the data structure.
