I am trying to subtract one from a variable that is being passed through a portal. The variable is a year and comes back as a string. Every time I try to subtract one it gives me an error on the -. I have tried numerous ways but cannot find one that works. Any ideas on a better way to do this?

-DEFAULT &MBR_YEAR = '2014';
-SET &DATA_YEAR = &MBR_YEAR-1;

If you can guarantee that the variable is only numeric, then just add .EVAL to the -SET command.

-DEFAULT &MBR_YEAR = '2014';
-SET &DATA_YEAR = &MBR_YEAR.EVAL - 1;

Ahh yes that was what I was missing. Thanks for the help!
