LOOP
loop decreases CX by and jumps if CX is 0

mov CX, 5
seg:
	... ; will be executed 5 times
	loop seg


LOOP with additional checks:
LOOPE decrements ecx and checks that ecx is not zero and ZF is set
if these conditions are met, it jumps at label, otherwise falls through.

LOOPNE is same as LOOPE except that it requires ZF to be not set (i.e be zero) to do the jump.


  
JCXZ jump if CX=0

JCXZ next; if CX=0 do not delay
again:  
  
loop again  ; CX delay
