RE: Screen Refresh

["Mark A. Manske" <mmanske@xxxxxxxxxxxxxxxxxx>]

Sounds more like some other logic is the issue,
also, if you are going the direction it sounds like
you are, you are better off using write/read instead of
the exfmt function; it gives you more control of the
screen I/O.

Some code or parts would help, but here is what I would
ask myself (going on some assumptions here)
have I re-loaded the subfile?
If I am reloading the screen/subfile, are the records
updated/added to the file I am reading in?
Do I have any special parms on the compile:
rstdsp, dfrwtr, or dtaq (just as some examples)?
If I am not re-reading the file, am I updating
the correct field name for the DDS? been there too many times...
Is my lib list ok with the test version/if ILE have I done
(some may disagree with this) a rclactgrp *eligible - sometimes
you can have old code running in memory while testing -
there are better ways around this, but it is a quick "fix"...

Without seeing more code or knowing more specifics,
that is all I can offer for starters - most of this
can be seen if you run your debug interactively.

Subject: Screen Refresh


  I have a display screen that can possibly display 16 parts.  In most
cases, not all 16 slots are filled.  There is a possibility that the user
might want to add some new parts to the display.  When this happens, I call
another program which pops up a window just under the lowest line in the
display, or if the window would show up more than 2/3 of the way down the
screen, it pops up above the lowest line.  The window program is set up so
that once a part and quantity have been verified, control returns to the
calling program, which then adds the part to the display list.  At that
point I'm performing a WRITE to the display file, expecting to see that item
show up before I return to the window for another part.
  The problem is - that no redisplay occurs.  I'm still seeing the original
display screen, with a window asking for another part number.
  My question is - What do I need to do to make the new line visible before
I redisplay the part input window?  Obviously, a simple WRITE isn't doing
the job, and I don't want to do an EXFMT, because I don't want the user to
have to press another key inbetween keying part numbers.
