Thanks Michael,

I guess that’s a feasible workaround.

To all the other postings: I need the braces, since otherwise Stata thinks the global is $out_ , which it does not find to be defined, since the global reads $out_`year’, i.e. ${out_`year’}.

It would be nice if either the loops or the macros or better both would allow for different braces, i.e. “(“, “[“.

Best wishes
Hans

woops, I forgot about that requirement. You can also put the global into a local before using it (which may be helpful in other situations):

local outyear ${out_`year'}
foreach x in `outyear' {
...

Braces are also necessary when the global name contains a local macro...

. local loc a

. global ga hello world

. di "$ga"
hello world

. di "$g`loc'"
a

. di "${g`loc'}"
hello world

This was the case in the posted query... as I said in my previous response (which doesn't seem to have arrived yet more than an hour since I sent it) the -foreach x of global g- construct solves the problem.
