George,
I've run into that before - it's probably network latency. If there's
nothing in your keyboard buffer, your routine will bail. If a
multi-character keystroke gets broken between packets, that can happen.
Experiment with a delay before the INPUT TEST,-1 to allow the network to
catch up with you. It takes some tweaking, but faster hardware lessens the
effect. Of course, if you're not networked in any way, then I'm probably all
wet. I've been there before.

s to allow
the user to move from field to field, and the insert key would function as e

Because I was only taking one key at a time, I had to use KEYIN (otherwise back

character of the key.
Most of the time it worked, just everynow and again, it would blow up, and I co
uld never
figure out why (although I was told it was most like something in the keyin(
) internally).
The gist of the routine is below: It requires you to roll your own input routin
e, that is
you have to check for an "ENTER", and check for a "backspace", then remove the
last char
from BUFFER.
1000:
INPUT TEST,-1:
LOOP WHILE(TEST="1") DO
BUFFER=BUFFER:KEYIN()
INPUT TEST,-1:
REPEAT
RETURN

Subject: [U2] UV Timed INPUT
I'm sure I've seen something about this recently, but I've searched the
past 2 years with no luck. I want to do a timed INPUT in UV - if after
n
seconds the Enter key hasn't been pressed, do something.
Anyone got any clever ways of doing this ?
Thanks,
