You have your finger on the main issue. Try
foreach name of varlist xyz* {
local code = substr("`name'", -3,3)
label var `name' "indigenous input # `code'"
}
That is, you want to work on the text string
which is the name, not the contents of the variable
it names. Note also the distinction between
name
and
`name'
and a spelling fix.
