RE: Change Display File / CHGDSPF

>What resets the time out (WAITRCD) parameter of this?

Nothing automatic; there's no system facility to execute a CHGDSPF every so
often.  Even a release upgrade won't touch the attributes of your display
files.

I guess I'm confused by what "time out on her" means in this context.  It
won't be the first time I've been confused!

The behaviour you're describing sounds like a Windows screen-saver.  The
iSeries doesn't know that the user is typing until an AID key (Enter, Help,
CFxx, etc.) has been pressed.  Then the entire display's worth of data is
pumped back to the program all at once.

You can have a session time out, controlled by either TCP/IP or by
QINACTITV.  This usually results in a new sign-on display.  You can have a
READ request time out, controlled by WAITRCD.  This usually results in a
major 03 return code which the program can detect, or an error message if
the program isn't handling errors.  You can have an object lock time out,
controlled by WAITFILE.  This can be handled by the program, or an error
message if the program doesn't handle.
