8.10 Character String Processing Instructions
 Operation errors
 In the following cases, an arithmetic error occurs, the error flag (SM0) turns ON, and an error code is stored at SD0.
- The ASCII code of each position designated by (S) to (S+5) is a value other than "30H" to "39H", "20H", and "00H".
(Error code: 34)
- The ASCII data designated by (S) to (S+5) is outside the following range. (Error code: 34)
- When DABIN instruction is used: -32768 to 32767
- When DDABIN instruction is used: -2147483648 to 2147483647
- The range of the device designated by (S) exceeds the relevant device range. (Error code: 82)
