Function: Logical OR for bit variables
Description:
Set the carry flag if the Boolean value is a logic 1; leave the carry in its
current state otherwise. A slash (“/”) preceding the operand in the
assembly language indicates that the logical complement of the
addressed bit is used as the source value, but the source bit itself is not
affected. No other flags are affected.
