Grabbing Multiple Variable Labels

[Jared Greathouse]

Suppose I want to get the names of the list of covariates included in a model to display it to users.

sysuse auto, clear
cls
foreach x of var foreign price {
local x : variable label `x'
di "`x'"
}

This displays them separately, but what I want is to iteratively combine each variable label such that they're alongside each other like "Car Origin", "Price". How might I go about this?

sysuse auto, clear
cls
local wanted
foreach x of var foreign price {
    if `"`wanted'"' != "" {
        local wanted `wanted',
    }
    local wanted `wanted' `:var label `x''
}
display `"`wanted'"'

This approach of putting -local wanted `wanted' whatever- inside a loop is a very useful idiom for building lists iteratively in Stata.
