I was beginning to think I was insane or that my computer had faulty RAM or something :) We agree then. Do you think 48 bits could do it? Probably. But it's not worth the effort, now that you (and I) already have a 64-bit type. The PawnHashTable doesn't need to be "big" anyway. You are saying that Bruce uses 32-bit keys. Is this true? He has the problem too, then. /David
