Day 10

Looping

	Yep, Looping. This is most similar to a FOR loop in High Level Languages.

The LOOP Instruction
	The LOOP instruction works like so:
	
	mov cx,200  ; note that without 'h' that 200 is a decimal value (base 10).
AdditionLoop:
	add ax,3
	loop AdditionLoop ; will add 3 to AX, 200 times.

Each time LOOP is executed, CX is decremented and if it's not zero, the label specified is
jumped to.

DEC and INC Instructions
	Now would be a great time to tell you about DEC and INC.

	DEC subtracts 1 from a register or memory location and INC adds 1.

	Examples:

		inc ax ; AX++; or AX = AX + 1;
		dec dx ; DX--; or DX = DX - 1;

		var dw 0
		dec var  ; should work, I think. var--; or var = var - 1;

This Day In Review

	I'm running out of easy instructions. Look for output oriented stuff soon!

	Happy coding!,
