Re: st: reshaping + info from label

I guess the way I named my variables variable1ab etc is misleading.
Say its varz vary varx etc (having the labels "A B",  "C D",  "E F"
respectively and I would like to have 2 variables newvar1 and newvar2
that contain the identifying info in the labels of the original
variables)
Hope the problem is better explained now?
