Deleting macro variables

All

I know how to find and delete macro variables from the global symbol table with %symexist and %symdel.

For example:
%if %symexist(NewFileName) %then %symdel NewFileName;

But how can I search for the existance and delete a macro variable from a local symbol table. I'm at a loss.

Any ideas?

It's supposed to, by design.

Locals local to the macro and are equivalent to stack variables.

If you need persistence, then use a global variable.
