I'd tweak this a little.
This is going to fail when Stata is asked to
rename foo foo
and it could also -rename- variables
which you are happy to keep with their
present names. So, use the most restrictive
varlist you can specify, say:
foreach v of var _* {
local V : subinstr local v "_" ""
rename `v' `V'
}
That said, to this solution from first principles
should be added two other suggestions:
1. Following Ada Ma's post, note that -renpfix- is already
in Stata as an official command. (Oddly, the complementary
-rensfix- remains user-written and outside official
Stata.)
2. Also -renvars- (-search renvars-) remains on offer
as a general renaming tool.
