There is a way to make the screen "auto refresh" but be careful, It is on
a timer that you set and removes the keyboard buffer. Function keys and
the enter key when pressed at the wrong time will cause program errors.

If by "removes the keyboard buffer" you mean that data typed onto the screen by a user is lost, then
you are incorrect.

You can set things up so that the screen gets refreshed without losing anything the user had already
typed.

"Following INVITE is the PUTOVR (Put with Explicit Override) keyword. PUTOVR is not necessary for
effecting a time-out, but using it is often desirable so that when your device times out you don't
lose any input you've already typed. PUTOVR works in conjunction with the OVRDTA (Override Data) and
OVRATR (Override Attribute) keywords. You typically use these keywords to reduce the amount of data
sent to a display when the record format you're writing is already on the display. When PUTOVR is in
effect, the system sends to the display only those fields for which OVRDTA is also in effect. OVRATR
works in a similar fashion for display attributes. In the example, you can see that indicator 11
conditions OVRDTA. I can therefore write the record with indicator 11 set off so that the system sends
no data to the display when I write the record again after the time-out and anything already typed on
the display remains there."
