RE: Display problems CPF5192 with mouse clicks

If I understand the problem rightly (no guarantee!) then I believe you need
to condition the DDS keyword SFLDSP so that you only try to display the
subfile when there are entries in it.  Here's what I typically do:

* clear subfile
SFLDSP off
SFLDSPCTL off
write control
sflrrn = 0
sflrcdnbr = 1
SFLDSPCTL on

* load subfile.  If no records read, note
* that SFLDSP indicator remains off.
position cursor (setll/chain, etc.)
loop
  read record
  eof? exit loop
  add 1 sflrrn
  SFLDSP on
  write subfile record
repeat

* display subfile control/subfile
exfmt control
