6 BASIC INSTRUCTIONS
6.5 Data Conversion Instructions
Converting decimal ASCII to 32-bit binary data
DDABIN(P)(_U)
These instructions convert the decimal ASCII data in the device numbers specified by (s) and later to 32-bit binary data, and
store the converted data in the device specified by (d).
■Descriptions, ranges, and data types
■Applicable devices
*1 T, ST, C cannot be used.
• These instructions convert the decimal ASCII data in the device numbers specified by (s) and later to 32-bit binary data,
and store the converted data in the device specified by (d).
When the ASCII data, -1234543210 (signed), is specified by (s)
• The ASCII data that can be specified by (s) to (s)+5 is -2147483648 to +2147483647 for signed data, and 0 to 429496729
for unsigned data. The data stored in the high-order byte of (s)+5 is ignored.
• As signed data, "20H" is stored if the ASCII data is positive, and "2DH" is stored if the data is negative. (If a value other than
"20H" and "2DH" is set, the data will be processed as positive data.) (DABIN(P))
• A value "30H" to "39H" can be set in the each place of the ASCII code.
• If a value "20H" or "00H" is set, the value will be processed as "30H".
