Re: Can a SubProcedure know the name of a variable passed to it ?

Hi, John:

Try to explain the rationale for what you are trying to do and why (from the application's point of view.)

Then perhaps we can offer some meaningful suggestions?

Thanks,

Mark S. Waterbury

IsBlank or the variable was named IsNotBlank.

I don't know how I can differentiate the two in the SubProcedure
unless IsBlank is not just a boolean, but actually a structure that is
composed of a boolean followed by a text field that carries the name
with it, so that it can be interrogated.
D IsBlank DS
D Boolean N Inz(*On)
D Text 10 Inz('IsBlank')

I suppose there is the other way, which is to make IsBlank not a
value but a Subprocedure IsBlank() and then use Procptr to decipher
the name.
