This was just discussed in another thread. This is not always forced by FPC. eg: var S: TMyArray; pS: ^TMyArray; then use them as follows: S[2] pS[2] Both work just fine without dereferencing the second line. Weird behaviour, but true. > Lastly, passing by reference rather than by value is much faster. > Since copies need not be made when entering a method when entered OK, so this is only a benefit then if you use Arrays. If I had to use a simple data class (class with no methods), then I can simply pass it as normal or via 'var' parameters and get the same result as you mentioned. -- Regards, - Graeme - _______________________________________________ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
