True - VALUE always makes a copy of the variable. However it can only be applied to procedure calls.

Kurt Anderson pointed out, the value of a const parameter can be changed
by directly referencing a global variable.

The value of a global variable can be changed from within a subprocedure period. The CONST bit is a red herring in this case.

Which is a behaviour of CONST, pass by reference....

Yes - but as I and others have also pointed out - the danger of CONST is that the _real_ reference is passed when the size/type match exactly. That is why I would like a COPY option.
