Thanks group, This is exactly what I thought of while taking a short break (DMV to get renewed). I need another cup of coffee.

Set var vd1txt TEXT = null Set var vd1txt = (ctxt(.vd1)) If vd1 exists and has a value, vd1txt will change from null to whatever. If it doesn't exist, the second set var line will cause an error, but with error messages off, you won't see it and vd1txt will still be null.

I'm trying to pass parameters that may not exist. So if they dont exist create them. I've tried IF vd1 EXISTS THEN SET VAR vd1txt = (CTXT(.vd1)) ELSE SET VAR vd1txt = NULL ENDIF but since vd1 doesn't exist it errors out. Turning off error messages doesn't help. So is there a way to create a variable based on the fact that another variable exists or not? Jan
