 Operation errors
 In the following cases, an arithmetic error occurs, the error flag (SM0) turns ON, and an error code is stored at SD0.
- When BCDDA instruction is used, the data designated by (S) is out of range of 0 to 9999. (Error code: 34)
- When DBCDDA instruction is used, the data designated by (S) is out of range of 0 to 99999999. (Error code: 34)
- The range of the device designated by (D) exceeds the relevant device range. (Error code: 82)
 Program example
