In addition, it may be worth knowing about -label language-.

Also, if the long labels were ever thought good, you might want them again in the future, so various ways of backing up might be considered.

Suppose you want to replace "University" by "U" in a bunch of variable labels.

foreach v of var * {
        local label : var label `v'
        local label : subinstr local label "University" "U", all
        label var `v' `"`label'"'
}

The key stuff here is documented at help -extended_fcn-. As Maarten was remarking only the other day, it's sometimes easier to remember to go to the help for -macro- and then jump.

-varm- is good for doing this for a few labels.

Liao, Junlin

Does anyone know how to read out variable labels? For example, I have a group of variables with long labels. I want to programmatically shorten the labels by replacing keywords. How do I get the variable labels in functions?
