[Description] Changes the memory switch specified by a to the value specified by b. When b = 48, the memory switch is set to OFF. When b = 49, the memory switch is set to ON. When b = 50, does not change the memory switch. When a = 2,Memory Switch 2 is set as follows: MSW 2-1 to 2-8 2-4 to 2-8 Setting value (b) 48 48 or 49 Function Reserved Default code page setting(refer to setting the Memory Switches ).
