RE: Window in 2nd pgm?

I've never had to deal with this but is there some reason for not declaring and using an INFDS for the DSPF? Seems a lot easier than dealing with the API.

DEV_TYPE CHAR(1) POS(272); // Device type - *DS3, *DS4, etc.
NUM_ROWS INT(5) POS(282); // Number of rows
NUM_COLS INT(5) POS(284); // Number of cols

Sorry...been to long and I was mis-reading the API name...

QsnRtvMod - lets you determine if the current screen (last output) is 80 or
132 column
QsnQryModSup - lets you determine if a device is configured to support 132
columns

Yes the code Mark linked to shows the check being called from the popup
window.

TLDR;
The key to making our popup window display in the correct mode requires
the following steps:


1. The (popup) display file should be user open (UsrOpn on the F spec)
so that we can set the size mode before the file is opened
2. Detect the current screen mode size by using the
Screen_SizeIs27x132 functio
3. Set the display mode size of our popup window program to the
current mode
4. Open the display file
5. Display the popup screen

Ignore what's being done in the test driver.

The QsnRtvMod API mentioned by another poster won't work, it simply tells
you if a display supports 27x132.
I've used that to display a message asking the user to call the help desk
to get their session reconfigured as I had a new application that only
worked on 27x132.

HTH,
Charles

After reading the doc, I'm not sure if that API called from the window pgm
will detect the screen of the calling program. I'll have to test it and
see. We may have to add an optional parm to the window pgm to override
the
default display size.

Thanks

Justin,
The QSNRTVMOD will give you that information.
Sample code can be found here:
