RE: text entry widget?

["Bale, Dan" <DBale@xxxxxxxx>]

I struggled with this several years ago.  You're right, CNTFLD has its
limitations.  If you're thinking of a Windows-centric type text window
(think Notepad), forget it for the green screen.  If your CNTFLD is 300
chars long, then that's your max.  What I managed to do was to design a new
display format that basically was one CNTFLD of 18 lines (1440 characters);
this happened to be more than enough for my client at the time.  Also,
there's no word-wrap on the entry window, just character-wrap.  There is a
word-wrap keyword but that only works for output-only.

I know there are OfficeVision APIs that could be used to effect some of what
you're looking for, but we all know where OV is headed.

If you really want a Windows-centric type text window, you'll have to go to
VA-RPG.
