using GET_KBRD [message #8305]

Hello All,

I have what should be a simple problem. The following 3-line program:

REPEAT BEGIN
A = GET_KBRD(0)
PRINT, BYTE(A)
ENDREP UNTIL A EQ 'q'

exits when the user types 'q'. However, remove the print statement,
and the program runs indefinitely regardless of any user input!

Anyone know what's wrong. I'm running IDL 4.0.1 on a PC.
Also, to get around this problem in a large program that I wanted the
option to exit from (ctrl-c doesn't usually work from a PC), I went
ahead and used the print,a--but it took several passes in the program's
loop before the keyboard buffer was read. I also tried to flush,0 the
keyboard buffer to no avail.

Thanks in advance,

Walid
