So in effect it means that all of these calls are exactly the same: FillArr(const Arr: TByteArr) FillArr(var Arr: TByteArr) FillArr(Arr: TByteArr) At least as long as the FillArr function does not attempt to change the ponter itself like this: Arr := SomeOtherArr; In which case I guess that the only version that will carry this back to the caller is the var version? But that is not what I am doing at all, so I can stick with a simple: FillArr(Arr: TByteArr) and be sure that I will not get back a different array, but instead get my array filled as requested... -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
