Thank You I found the sleep procedure Thank you for explaining that it was looking for a pointer, that was helpful. A little cutting and pasting and now I have 3 more ways to sleep... Sleep_S will probably be sufficient and is the most flexible, because if you have 1,000,000,000 seconds you

[fpc-pascal] Microsecond Delay Suggestions?

Any Suggestions for a microsecond delay? I had a scheme in my old dos program where I would run a massive loop at the beginning of my program and time it with DOS 55mS ticks, then do the math and figure out how many times I needed to loop for a given delay.. worked great on DOS with nothing
