That is not true. This program prints "2" when compiled under Turbo

The behavior is dependent on the {$T+} (typed pointers) mode.

I thought that adding something to a pointer always adds 1 sizeof(byte) to it.
So if something is added to a pointer the compiler looks the sizeof the
(typed) pointer points to?

So you're allowed add an integer to an untyped pointer?!
Wow!
Usually if you add 1 to a pointer of type t, then sizeof(t) gets added
to the value of the pointer. So if p points at an array of byte, p+1
would point at the next element of the array, 1 byte after p. But if p
points at an array o
What is the difference between A* and B*?

says that it takes for a priority values from -15 to 15. The comment
to the right of the declaration says that "0" is normal. Are these
numbers like nice's, where negative numbe
