John and Claude,
That fixed it. Thanks. Didn't think that F2 was "reading" F5. I'm sure you know what I was trying to do--when you get a partial, send what you have and end with a question mark.
I do understand that with the pgm all you need to do is fix the call and it will go back and correct the call upon your F3 (TU) response. This is a great feature.
As always, the Help is terrific in this group. Thanks again!
