Dear listers

I want to do generate a new var from the last 11 character of a string variable. I normally count the possitions that i want and use the substring command, but my oldvar has contains different number of characters. The first position of interest maybe nr 1 in some observations and number 15 in others. 

Whats the best way to do this?

Lars
