Function and operation explanation
1. 16-bit operation (DABIN/DABINP)
1) Data expressed in decimal ASCII codes (30H to 39H) and stored in the device specified by is
converted into 16-bit binary data, and stored in the device specified by .
For example, when the device specified by stores ASCII codes expressing "-25108", 16-bit binary
data is stored in the device specified by as follows:
2) The numeric range of data stored in the device specified by is from "-32768" to "32767".
3) As "sign data", "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".
2. 32-bit operation (DDABIN/DDABINP)
1) Data expressed in decimal ASCII codes (30H to 39H) and stored in the device specified by is
converted into 32-bit binary data, and stored in the device specified by .
For example, when the device specified by stores ASCII codes expressing "-1,234,543,210", 32-bit
binary data is stored in the device specified by as follows:
