Converting character string to 16-bit binary data
VAL(P)(_U)
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).

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.
• The total number of digits stored in (d1) is the total number of characters (including the sign and decimal point) representing
the numeric value. The number of digits in the decimal part stored in (d1)+1 is the number of characters representing the
decimal part after 2EH (.). The 16-bit binary data stored in (d2) is binary value converted from a character string with the
decimal point ignored.
