No, it just checks whether input (Enter/PA/PF) is available. 
Early versions of TSO, under MVT, had problems handling this, 
but MVS should work as expected,

Not really. What would load it is if you tried that in a loop, 
as opposed to using a TIME WAIT macro (with an exit) to retry.

To date I've used Tom Brennan's Vista, Blue Zone, and QW3270 
without any problems. The only one I've had problems with is the 
c3270/wc3270 code; I first installed the complete tk3, and got 
odd sized Windows windows, with the cursor being in the wrong 
place, and things not displaying when the screen was updated. 
But I also used larger screen sizes (43*80 and 27*132), and the 
problems might have been fixed since then.
