STATA: Locals in global names

> i have a series of globals with the names: strata_pop1 strata_pop2
> strata_pop3, etc. all the way up to strata_pop21
> i'm trying to reference the values stored in each with a loop
like this:

> display $strata_pop`i'

The solution is simple: Enclose the global in curly braces, like this:
display ${strata_pop`i'}
