 Operation errors
 In the following cases, an arithmetic error occurs, the error flag (SM0) turns ON, and an error code is stored at SD0.
- A character other than "0" to "9" is put in the data of (S). (Error code: 34)
- The range of the device designated by (S) exceeds the relevant device range. (Error code: 82)
 Program example
 The following program converts the sign and the decimal ASCII data set to D20 to D22 to BCD 4-digit data, and stores the
result of the conversion at D0.
