Eric gave one answer.
A second is to check out -macval()-.
A third is to report that in my experience as a programmer most of the interest in doing this arises from a misconception that it is necessary. It is, I assert, usually unnecessary and poor Stata programming style. But only a description of the underlying problem could reveal whether that applies in this case.
A search of the archives for "delayed substitution" will reveal pertinent threads.
