st: RE: Using value labels to create varlist

["David Radwin" <dradwin@mprinc.com>]

Yo Jack,

Try extended macro functions within a -foreach- loop, like:

foreach v of varlist * {
	if "`: value label `v''" == "LABBG" mvdecode `v', mv(5 6)
	if "`: value label `v''" == "LABA"  mvdecode `v', mv(3)
	}
