Re: thanks hamberg: prob in deleting records using a subfile from a pf.

To loop throught the confirmation screen use CHAIN and use a FOR loop based on 
the number of records in that subfile, as another person suggested, from the 
INFDS for the display file.

UIM is documented in the manual I listed, the "Application Display Programming" 
manual - there was, I believe, a book on it from MCPress or someone but might 
be out of print. Lots of folks use UIM panel groups for help text - that's 
pretty easy to do - but application screens are tougher. There is also no 
graphical or SDA-like design tool.
