FPC mode is the default and (I believe) allows function overloading and structured return values (with slightly different function pointer syntax). > I am not that interested in Turbo Pascal compatibility, so I can not say > anything about it.

Sometimes they frequent the BTTR Forum too. _______________________________________________ Freedos-devel mailing list Freedos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-devel
