I took the do out but now it is doing nothing. can you help me figure out why.

Thanks for any help

The SAS log would be much more useful than seeing the SAS program code.

Here's the OPTIONS statement you want to use to get the most diagnostic output:

OPTIONS SOURCE SOURCE2 MACROGEN SYMBOLGEN MPRINT /* MLOGIC */;
