Processing details
• These instructions convert the character string in the device numbers specified by (s) and later to 16-bit binary data, and
store the number of digits in the device specified by (d1) and the binary data in the device specified by (d2). When
converting a character string into binary data, the data from the device number specified by (s) to a device number storing
"00H" is handled as a character string.
