It is interesting to notice that this modified code won't work either unless the "set" statement is left for the end, just before the "run" statement. I'm still not sure of why this is, but it obviously have to do with Victor's comment about SAS PC not accepting an empty dataset in the "set" statement. As far as I know, you can do it in the mainframe. Ed
