Hi, quick question, how do you get around the problem of the user pressing a key once, but the actual action playing numerous times on one key press?

I can't use the WAIT command as this stops my whole programme.

Use a timer of some sort.
Example:

+ Code Snippet

timer#=0
do
if upkey()=1 and timer#=0
print "Hi"
timer#=100000
endif
if timer#<0 then timer#=0
if timer#>0 then dec timer#,1
loop

Just edit the "timer#=100000" to your liking.
There is probaly a more efficient way though because this is the only way I know.

The timer like shark said should work fine. What I usualy do is similer but with a hold variable like so:

+ Code Snippet

Hold = 0

do
if upkey() = 1 and hold = 0
print "hello"
hold = 1
endif

if upkey() = 0 then hold = 0
loop

yeah I do what Justin W does, make a flag, so when you press the key it activates and if the flag is active then it won't read it again, but if you release the key then the flag resets.
