I find the best way to control speed is by throwing a dummy loop in
somewhere. For example, suppose I want to slow down the operation of FN
doSomethingSlowly.

LOCAL FN doSomethingSlowly
FOR blegh = 1 TO 100
FN DoCoolAnimationEffects
FOR dummy% = 1 to 100 'dummy loop to waste time
NEXT
NEXT
END FN

Of course, this gets unpredictable as machines get faster, so instead, you
could do:

LOCAL FN doSomethingSlowly
FOR blegh = 1 to 100
FN DoCoolAnimationEffects
DELAY delaytime% 'delay specified num of ticks
NEXT
END FN
