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


I am building a Subprocedure that would be nice to know if one
of the argument passed to it was the variable named
IsBlank or the variable 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.
