Agreed. It's not readable at all. So don't do that, instead

{$IFDEF BIG}
type My_Type = SmallInt;
{$ELSE}
type My_Type = ShortInt;
{$ENDIF}

and then

|Inc (My_Type(v), Delta);

should do the trick.

OTOH, to be honest: I don't see the point in using Inc/Dec here at all, 
especially if "v := v + Delta;" would work perfect already. I even 
think the "standard" way of doing the addition would be much more 
readable in that context.
