For the example posed by Toby, the variable Match will yield either a 1 or 0 depending on the expression within the parentheses.

To truncate one SAS variable's value when it matches another, you would need to use SAS functions SUBSTR, INDEX and LENGTH in a DATA step along with your two variables. Give it a try and send back your code to the group for feedback.
