ORL does a bitwise OR operation between operand1 and operand2, leaving

the resulting value in operand1. The value of operand2 is not affected. A logical

OR compares the bits of each operand and sets the corresponding bit in the

resulting byte if the bit was set in either of the original operands. Otherwise,

the resulting bit is cleared.
