Loop

[Marc Audrna]

I want to change the name of fields in a loop. For example, how can I delete the last two characters of the fields if they end by 20 ?
I could do it without a loop :

rename (var20 var020 varz020) (var var0 varz0)

but it will be error source in copy paste.

Thank you !

I didn’t know "*" could be used with Stata...
