Re[2]: ? on overlay and stupid DDS keyword tricks

     Take a look at Dynamic Screen Manager APIs. Pet peeves are 
     optional...... (Just what does one feed a peeve anyway?)

Thanks, Mark.  
 
This is much simpler than my solution.  It also works.   I'm swearing off
the use of ASSUME in this situation.  
 
My particular need was to put a list of stuff in a subfile and have a total
for one column of the subfile always visible below the subfile and have this
appear in a pop up window. Wouldn't it be simpler if you could put the
subfile control record above or below the subfile. 
 
This leads to a pet peeve of mine concerning DDS keywords and display
programming.  I prefer to use the fewest  DDS keywords and indicators
possible so my code is readable (to me a week later, let alone others.)  It
irks me that I can't do this programatically and have to rely on magic
words.  Consider test based screen programming on the PC (all right, no one
does it any more) where screens were 2000 characters and it was up to you to
put them there.  Admittedly it takes more code to do this, but you can do it
all in a program and document it.

The keyword you need is OVERLAY....but....you may also need CLRL(*no) if
your second screen overlays any attribute byte on the original screen.
I.E.
 
If you write a header format and then exfmt a SFL(SFLCTL) screen you would
only use OVERLAY.
If you wanted a screen in the middle of a previous full display you would
need both OVERLAY and CLRL(*NO).
 
I do not believe you need to use a dummy blank screen or the ASSUME keyword
to achieve this.
 
Hope this helps.
