>>Ron,
>>inkey(0.1) means wait for a key for 0.1 seconds at max, not wait 0.1 secs before checking a key. You'd need a loop as you did to enforce it, however using seconds() is dangerous if this routine could be running around midnight (SECONDS() - pnseconds > pntimeout would be true about 24 hrs later).

Yes Nick,
Second is better. Datetime() can't resolve small amounts.
(Actually I would use a C based timer like Bela Bodec's cpptimer to be precise enough:)
