RE: Subfile HELP!!!

I figured it out.  

First of all, to populate the subfile, I wasn't using EXFMT, I was using
WRITE to the subfile format -- not the subfile control format.  I was doing
this in a DOW loop, reading from a physical file, then WRITE ing to the
subfile.  

Then, to display the subfile, I was using EXFMT on the subfile control
record, which was working.  If Enter was pressed, I was deleting the records
in the corresponding physical file that matched the subfile record, then
once again stepping through the physical file populating the subfile, then
doing another EXFMT on the subfile control format.  

After doing a trace, I realized that it was this SECOND EXFMT (same
statement, second time calling it) that was causing the error...

The problem -- I wasn't taking any action to reposition the physical file
before reading through it again to populate the subfile, so it had zero
records in it (ROOKIE!!!).  

Thanks to all for your help, I appreciate it!
