Dear statalist,

has anybody an idea how to solve the following problem?


foreach x in ${out_`year’} {
do something
}

That is: I have several globals and I need the braces to tell Stata that the local `year’ actually belongs to the global name.

Now I would like to run a loop over all elements in the global ${out_`year’}.

But the foreach command gets puzzled with the braces around the global, since it thinks that this means to start the loop. And this returns an error that a code follows on the same line as open braces.

How can I separate these braces?

Thanks
Hans
