Re: st: Renaming variables using foreach

[Suryadipta Roy <sroy2138@gmail.com>]

Dear Nick and Steve,

Thank you very much the help! Actually, I forgot to mention that I am
using Stata 11.2, and what I really wanted to do was to "label" the
variables with the existing variable names (since the current variable
names from the World Develepment Indicators are too long). The idea
was thus to change the long names to var1, var2, etc, and then use
-label- . I would now check if I can somehow manage to get the
variables labelled by their variable names (obviously I can do that
manually as well) in Stata 11.

And, Nick's solution works and will read into it very carefully.

Thanks again!
Suryadipta.
