Conversion from ASCII to hexadecimal BIN
HEX(P)
Processing details
• Converts the number of characters of hexadecimal ASCII data designated by n stored in the area starting from the device
number designated by (S) into BIN values and stores them in the area starting from the device number designated by (D).
For example, if the number 9 has been designated by n, the operation would be as follows:
(S): Head number of the devices where a character string to be converted to BIN data is stored (character string)
(D): Head number of the devices where the converted BIN data will be stored (BIN 16 bits)
n:
(D): Head number of the devices where the converted BIN data will be stored (BIN 16 bits)
n:
Number of characters to be stored (BIN 16 bits)
