I acknowledge the limitations of this approach.. maybe it would be easier to just stick a 1 sec delay before the randomize :) You could use a number from /dev/random or /dev/urandom to initialize randseed (that's just a global variable in the system unit, which is the only thing that randomize() changes when you call it), instead of randomize(). Then you'll get the best of both worlds. Jonas ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal

Do you know the difference between the Real1() and Real2() etc. methods? The 1.9.x FPC rtl already uses the Mersenne Twister. However, that doesn't change the need of having to get an initial random seed from somewhere. Jonas ___ fpc-pascal maillist - [EMAIL PROTECTED] http://lists.freepascal.org/mailman/listinfo/fpc-pascal

It compiles because it has the meaning that David said. The "not"
operator is applied to fmt[i].

The "not" operator applies to integers, performing a bitwise not. In
your code it's applied to a character, so the conversion is probably
from char to integer. Useful when doing f.i. compression or
encryption.
If it's inappropiate or not, I don't know.
