In the past I fell into the trap of declaring almost all of my variables as
global ones as I only had a handful of them, but now the list keeps growing and
I have begun looking to passing arguments as perhaps a better method of writing
for memory considerations as well as just nicer looking code.
 
Are there any potential "GOTCHAS" when one uses the same variable to pass to
a procedure that is returned by the procedure?  I have played with this on a
very limited basis with Functions and would like to expand to Subprograms so
far without any known problems.
 
Thanks.
