>From what I remember TP doesn't, and it was to introduced first to FPC to disambiguate using the returnvalue of a function as function result, or calling that function recursively. IIRC TP couldn't use function result as rvalue. Later it turned out that Delphi also allowed it. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
