Re: st: is it possible to use local macros to define global macros?

Yes. The quick fix to this problem is to use the curly bracked syntax
${myglobal} instead of $myglobal:

global g1 foo
global g2 bar
forvalues i=1/2 {
   di "$g`i'"   // not what you want
   di "${g`i'}" // this is what you want
}

But I'd only do this if my code was already written with these
global/local combos and I didn't feel like changing it. I'm not sure
that I'd go with this design if I had to start from scratch.
