But it surely *is* smart enough to recognize that
Pack5P = Pack10P;
could be problematic?
If you mean that there's more than one digit difference in the precision
of the left-hand-side vs the right-hand-side, I don't think it would be
good to have a detect-overflow feature that missed this:
Pack5P = Pack6P;
If you mean that the right-hand-side is a simple variable, so the
compiler can tell it's not
Pack5P = Pack5P + 1;
then that's the kind of thing that the RPG compiler can't always tell.
By the time it gets to the assignment, it doesn't necessarily know where
the right-hand-side came from.
