Re: st: how to rename a set of variables using foreach

[Ekaterina Hertog <ekaterina.hertog@sociology.ox.ac.uk>]

Dear Nick and Phil, thank you very much for the advice.
I use Stata 12.1 and Nick's solution worked perfectly.
I also managed to tweak Phil's solution so it works by renaming inccat1 
and inccat2 manually before doing the transformation.
