Thank you Matt,
Sure it works but unfortunately my variable numbers are not in a discipline as given in the example.
In my variable names there are leading "_" s followed by a "number" and "word" "_" "word"....
Here I want to take the first "number" and put it after the first "word" to get a sequence of "word""_""number" and do this by means of a loop. Do whatever my number or word is.
Thanks again. Have to wait some more help..

There might be a way to do this in one line using -renvars- (SSC), but even though I do this kind of rename frequently I think it's easier to write a quick loop than figure out the correct syntax.
