2. 32-bit operation (DDABIN and DDABINP)
1) Data stored in to +5 expressed in decimal ASCII codes (30H to 39H) is converted into 32-bit binary
data, and stored in [ +1, ].
For example, when to +5 store ASCII codes expressing "-1,234,543,210", 32-bit binary data is
stored in [ +1, ] as follows:
2) The numeric range of data stored in to +5 is from -2,147,483,648 to +2,147,483,647.
The high-order byte of +5 is ignored.
3) As "sign data" (low-order byte of ), "20H (space)" is set when the data to be converted is positive, and "2DH
(-)" is set when the data to be converted is negative.
4) An ASCII code for each digit is within the range from 30H to 39H.
5) When an ASCII code for each digit is "20H (space)" or "00H (NULL)", it is handled as "30H".

Errors
An operation error is caused in the following cases; The error flag M8067 turns ON, and the error code is stored in
D8067.
• When the sign data stored in is any value other than "20H (space)" or "2DH (-)" (error code: K6706)
• When an ASCII code for each digit stored in to +2(5) is any value other than "30H" to "39H", "20H
(space)", or "00H (NULL)" (error code: K6706)
• When the numeric range of to +2(5) is outside the following range (error code: K6706)
• When to +2(5) exceeds the device range (error code: K6706)
