command inc operand
Increases the operand by one.
The CF flag is not affected. The OF, SF, ZF, AF, and PF flags are set according to the result.
operand = operand + 1
Adds 1 to the operand, while preserving the state of the CF flag. The operand can be a register or a memory location. This instruction allows a loop counter to be updated without disturbing the CF flag. (Use a ADD instruction with an immediate operand of 1 to perform an increment operation that does updates the CF flag.)
