Should have mentioned this before, but Delay_ from dos.library waits in chunks
of 50ths of a second (on all machines). e.g. Delay_ x waits for x/50ths of a
second.

Maybe only the lower 32 bits would change, but you'd need to subtract the two
things different eclock values. Probably easier using the Delay_ :)
Actually, I just went to try the eclock method and found that the ReadEClock_
doesn't tokenise here. And ISTR devices being a bit broken in Blitz. Another
advantage of Delay is that it actually puts the program to sleep in a proper
multitasking way, whereas if you used the eclock, you'd have to do a busy-wait
loop to wait for x/50ths of a second.
