Re: st: How can I obtain the name of a variable's value label programatically?

[Nick Winter <nwinter@virginia.edu>]

See -help extended_fcn- for a discussion of the extended macro 
functions, including ": label", which is what you want.

For example:

local lab : value label foreign
levelsof foreign
foreach v in `r(levels)' {
	local vl : label `lab' `v'
	local vals `vals' `v'
	local labels `labels' `vl'
}
di "values: [`vals']"
di "labels: [`labels']"
