Set the memory to the extent of the memory range of each PC model. In case of using the [Bit Write] memory as the
bit device of the [Output Action] is [Momentary W], the other bits will be cleared when the bit memory is output,
because the [Bit Write] will be output by one word (refer to P5-10, reference 14-7 of ZM-71SE Instruction Manual).
Use [TYPE] number to assign indirect memory for macro programs.
