I didn't think the compiler would let you access string[0] directly anyway, even with range checking off - since that's a compiler thing - but I haven't checked for sure. (using i:=0; string[i] could work but calling setlength is fine for me for this purpose). _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
