RE: Variable file names

["Tim Kredlo" <TKredlo@xxxxxxxxxxxxxxxx>]

Scott,

The 'two  vars' solution worked.
Not really that ugly.
Doesn't seem like it should be that difficult, though.

Thanks for your help.

Unfortunately, files are always "global" in scope.  Therefore, you
cannot use a variable that's local to a subprocedure in your F-spec.

It should work if you define "Filename" to be global instead of local to
the procedure.   (i.e. define it in the D-specs above the main
procedure)
But, of course that'll defeat the purpose of the parameter to the
subprocedure.

You might think about having two vars...  "global_File" and "parm_File"
and then just before the OPEN of the file, set global_File = parm_File.
Ugly, I know, but it's about the best you can do unless you want to use
the ILE C runtime to access your file.
