(1): 00H is stored in the upper byte of (d)+5 only when SM701 (Number of output characters selection) is off, and 20H (space) is stored when it is on.
*1 When the value is 0 or positive, 20H (space) is stored. When the value is negative, 2DH (-) is stored.
*2 When the length of the numeric part is 9 digits or less, 20H (space) is stored in ASCII 10
*3 When the length of the numeric part is 8 digits or less, 20H (space) is stored in ASCII 10
*4 When the length of the numeric part is 1 digit, 20H (space) is stored in ASCII 10
