I tried that approach, however the only thing that happens is that it
"feeds" 0 and 1 through, not the var label. However when the var is
1/2 everything is OK. I find it strange that at least the 1-value
doesnt find its associated var val in 0/1 variables.
e.g.

capture program drop km
program km
local h
local g 1
qui levelsof `1', local(lev)
di `lev'
	 foreach val of local lev {
		
      	local k `:label `1' `val''
		di "`k'"
		local h `h' `g' "`1' `k'"
		local m `m' lab(`g' "`1' `k'")
		local ++g
}
etc
etc
