Re: st: Problem with temporary variable and macro suffix

[Nick Cox <njcoxstata@gmail.com>]

Works for me (in Stata 10.1)

Not quite documented, but temporary variables (used to) have names
beginning with __ and followed by 6 characters assigned by Stata, so
that you can (could) add suffixes in practice, although somewhere
Stata says that you shouldn't assume that you can do that.

That aside, this is idiomatic

foreach a in element1 element2 element3 {
      tempvar this
      gen `this' = .
      local all `all' `this'
}

followed typically by loops over `all'.
