; The following loop increments I until it reaches 10

ForILoop:	inc	I
		cmp	I, 10
		jb	ForILoop

; So does this loop.

		mov	I, 0		;Added this statement.
ForILoop2:	inc	I
		cmp	I, 10
		jb	ForILoop2


; So does this loop:

		mov	I, 0
ForILoop3:	inc	I
		cmp	I, 10
		jb	ForILoop3	;Corrected this statement.


; The following loop adds I to J until J reaches 100.
