Yes, for sure. > I > haven't worked out how to implement internal functions into the compiler yet, Fill* are not internal functions, so you just have to adapt the system unit. > and I rather clear it with you > guys first before I make such an addition.

I would provide only one version, after all, Fill* is only a very small part of the rtl, so shaving off a few bytes here does not matter and we are not in a 1k contest :) _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
