I would have expected that in that scenario (no sysutils) try..except or try..finally should raise a compilation error then. Since you teel the compiler to do things it cannot do? It would be Delphi incompatible of course ... B.t.w. (cannot test now, am at work): does it catc exceptions if any other used unit in the main program uses sysutils? I.o.w.: is it enough if sysutils gets linked in, or must it be in the unit/prgram that actually has the try..except/try..finally code in it? > Behaves like 3.2.0 on what platform?

Not a big problem for me (I don't think I have any usefull program that doesn't include the sysutils unit), it just made me curious. -- Bart _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-devel
