The basic LOOP instruction has the following syntax − Where, label is the target label that identifies the target instruction as in the jump instructions. The LOOP instruction assumes that the ECX register contains the loop count.
WebNote that the ECX register can be used as a loop counter in 32-bit mode. However, in this case, one has to use the instruction LOOPD instead of LOOP.
