you said count down looping....
so here is a count down variable
`sets the 'count' variable to 10
count=10
do
print count
dec count,1 :`decrements the count variable by 1 each time through loop
if count=0
count=10 :`if count becomes 0 then start over at 10
print "press a key for the next 10-1 numbers"
print " "
wait key
endif
loop
Now you are saying timer.....a clock timer is another matter
t1=timer()
seconds=0 :`keep track of seconds
countdown=10 :`set our desired countdown time
do
t2=timer()-t1 :`get elapsed time since our t1 timer check
seconds=t2/1000 :`timer() returns time in milliseconds, so we divide by 1000 to get seconds
cls
print "seconds=";seconds :`print elapsed seconds
print "countdown=";countdown-seconds :`subtract from our countdown number
if seconds=countdown
t1=timer() :`if our countdown number has been reached, reset elapsed time variable to start again
endif
loop
Make sure you try the code people suggest, study it, try your own modifications,
and post
YOUR code here for us to help with, and don't just ask for the code from us without showing some of your own code.
It's always best to try something yourself, then post your code when asking for help
Good Luck!
