7 APPLICATION INSTRUCTIONS
7.8 String Processing Instructions
■
Operation of when SM705 (Number of conversion digits selection) is off
Decimal ASCII data is stored in a fixed number of digits in (d) to (d)+2.
*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
4
.
*3 When the length of the numeric part is 3 digits or less, 20H (space) is stored in ASCII 10
3
.
*4 When the length of the numeric part is 2 digits or less, 20H (space) is stored in ASCII 10
2
.
*5 When the length of the numeric part is 1 digit, 20H (space) is stored in ASCII 10
1
.
Ex.
-12345 is set in (s) when the BINDA(P) instruction is used.
■
Operation of when SM705 (Number of conversion digits selection) is on
Decimal ASCII data is stored right-justified in (d).
The following figures show an example of a value of (s) and a value stored in (d).

(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.
Value of (s) Data of (d) to (d)+2 Value of (s) Data of (d) to (d)+2
• 0
• Positive value (1
digit in numeric
part)
• The upper byte of (d) is filled with 00H.
• Data in (d)+1 and (d)+2 remains unchanged. • Positive value (2
digits in numeric
part)
• Negative value (1
digit in numeric
part)
• (d)+1 is filled with 00H.
• Data in (d)+2 remains unchanged.

• Positive value (5
digits in numeric
part)
• Negative value (4
digits in numeric
part)
• The upper byte of (d)+2 is filled with 00H. • Negative value (5
digits in numeric
part)
• (1): (d)+3 is filled with 00H only when SM701
(Number of output characters selection) is off.
