(1): 00H is stored in (d)+3 when SM701 (Number of output characters selection) is off. When it is on, the value in (d)+3 remains unchanged.
*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 4 digits or less, 20H (space) is stored in ASCII 10
*3 When the length of the numeric part is 3 digits or less, 20H (space) is stored in ASCII 10
*4 When the length of the numeric part is 2 digits or less, 20H (space) is stored in ASCII 10
*5 When the length of the numeric part is 1 digit, 20H (space) is stored in ASCII 10
Ex.
-12345 is set in (s) when the BINDA(P) instruction is used.
