How accurate can the TIMER fuction be? I tried INT(TIMER*100) in the following snippet:

pause:
start! = INT(TIMER * 100)
stp! = start! + waittime!
DO
curnt! = INT(TIMER * 100)
LOOP UNTIL stp! = curnt!
RETURN

and it locks up. I tried using >= but that doesn't change much...

sounds like an infinite loop.
Since timer is based on the computer clock, it would probably be 24
hours until the statement would be true.

Works when I use *10.

You posted:

Code: Select all

pause: 
start! = INT(TIMER * 100) 
stp! = start! + waittime! 
DO 
curnt! = INT(TIMER * 100) 
LOOP UNTIL stp! = curnt! 
RETURN

Let's suppose that, at starting, TIMER = 4000.0, and waittime! = 10.
So,
start! = 400000 and
stp! = 400010

By the time you get to the end of your loop, some time has passed, and
curnt! may now be 400011, so that your
LOOP UNTIL 400010 = 400011
will not be true, and, from then on, it will continue to loop forever.

Your try of
LOOP UNTIL 400010=>400011
also produces an infinite loop. You must reverse your thinking, so:
LOOP UNTIL stp! <= curnt
which would read, for my example:
LOOP UNTIL 400010 <= 400011
which, since it is, stops the loop. That is, whenever the current time exceeds the stop time, the loop will finish.

Give it a try!
