Check to make sure you aren't using a very old version of the procedure file--one that dates back to when we were using parameters, not options (although I think the pre-model versions were still called CNDITION to fit the old 8-character filename constraint, rather than CONDITION).
Open up the condition.src and see what it describes for the syntax, and then make sure that's the copy of the procedure that is getting SOURCE'd in.
If you are still having problems, email your program and data files, and your copy of CONDITION.SRC to us at
support@estima.com. Be sure to include your RATS serial number and the version you are using (do Help-About RATS to verify that).
