1. How many characters long can a variable label be? Answer.
2. Can more than one variable be assigned a variable label in one label command? Answer.
2. No. Only one variable can be processed in a label variable command. However, you can use a command like foreach or forvalues to create labels for many similar variables in a single loop, which saves a lot of typing.
