In assembly, what does `PTR` stand for?

Question

and     dword ptr [ebp-4], 0

In assembly code like above, what does the term PTR stand for? I know their usage -- size direct

Answer 1

The point of this hint is to tell the size of the operand.

You're writing to a point in memory. As you're only giving a 0, it doesn't know if it should write a byte, or word, or doubleword. The dword ptr means "write a doubleword". Yes, it stands for pointer, because you put a memory address as destination.
