Maybe not the call, but changing or adding address encoding is quite realistic. I assume you tested your code for PIC cases (which are quite common on *nix?) http://en.wikipedia.org/wiki/Position-independent_code FPC supports PIC And of course finding a perfect starting point so that you don't find false positives when you find $E8 inside the address (change 1 in 256 obviously) _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
