Usage: REPE
REPZ
Modifies flags: None
Repeats execution of string instructions while CX != 0 and the Zero
Flag is set. CX is decremented and the Zero Flag tested after
each string operation. The combination of a repeat prefix and a
segment override on processors other than the 386 may result in
errors if an interrupt occurs before CX=0.
