Okay, I can tell you what these do.
KEEP: Normally when your program closes the display file, the screen is
blanked. KEEP allows you to keep the data on the screen after
the display file is closed.
USRRSTDSP: When you create windows, the system saves a copy of your
screen before displaying the window. When you're done with
the "exfmt" to the window record, the system automatically
restores the underlying screen. (effectively erasing the
window) USRRSTDSP tells the system NOT to restore the
underlying screen. (in other words, you'll restore it yourself)
OVERLAY: Lets you put one (non-window) screen on top of another. without
erasing the first screen.
None of these really have anything to do with cursor positioning, though
they do give some hints. Probably the application is writing more than
one record to the screen before accepting input. TN5250 may be taking the
cursor position from the wrong record format...
I hadn't thought about the licensing issues... I just wanted to try to
reproduce the problem by writing a program that does the same thing. :(
hmmmm....
