Re: st: foreach global macro not working with multiple macros

[Nick Mosely <mosely@uw.edu>]

Statalist,

Thanks, guys. That does work, Eric. Unfortunately I have about 100
macros that I would like to loop over. Their names all start with the
letter p, so I was hoping to do something like the following:

foreach y of global p* {

I wonder, what is the use of -foreach- with macros if you can only use
one at a time?
I guess I'll have to find another way.

Thanks again for your help,

~Nick
