ASCII representation of binary data types

Binary data types are input using a 2-digit ASCII representation of the characters in the hexadecimal range of 0-9, A-F. The characters A-F are not case-sensitive and you can add a leading 0x prefix to the string. You must enter an even number of bytes up to the maximum number of encoded bytes permitted, otherwise an error is generated. For example, 36 bytes are input to represent the binary18 data type. No spaces or other separators are supported.

Each 2-byte increment of the input string is stored as a single byte. For example, the 2-byte ASCII representation of "AB" in hexadecimal notation is divided into blocks of four binary characters, where 1010 1011 equals one byte.
