Well... just to I will know. A long time ago (Delphi 4) I learned: Always use 'const' for 'strings' because this is faster. Strings will be passed by reference. This remains true? eg: var str: string; procedure Foo1(const s: string); procedure Foo2(s: string); I know in Foo1 the 's' parameter is readonly and in Foo2 not. But Foo1 and Foo2 are different for the compiler at the level otimization, even I not change the 's' value inside the procedure? Thanks and sorry for the newbie question ;-) Marcos Douglas _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
