Any 8-bit byte value may be encoded with 3 characters: an = followed by two hexadecimal digits (0–9 or A–F) representing the byte's numeric value. For example, an ASCII form feed character (decimal value 12) can be represented by =0C, and an ASCII equal sign (decimal value 61) must be represented by =3D.
Eventually, as 8-, 16-, and 32-bit (and later 64-bit) computers began to replace 12-, 18-, and 36-bit computers as the norm, it became common to use an 8-bit byte to store each character in memory, providing an opportunity for extended, 8-bit relatives of ASCII. In most cases these developed as true extensions of ASCII, leaving the original ...
This field has a minimum value of 3 (2 for 16-bit address field plus 1 checksum byte), and a maximum value of 255 (0xFF). "00" / "01" / "02" are illegal values. Address - four / six / eight hex digits as determined by the record type. The address bytes are arranged in big-endian format. Data - a sequence of 2n hex digits, for n bytes of the ...
In a Sinclair BASIC program numeric constants are stored as ASCII followed by a 0x0E byte and a 5-byte binary floating point representation. When listing a BASIC program only the ASCII part is used but at runtime only the binary representation is used. Some Spectrum programs exploited this to obfuscate numbers, while others did so to save ...
Byte Strings are encoded as <length>:<contents>. The length is the number of bytes in the string, encoded in base 10. A colon (:) separates the length and the contents. The contents are the exact number of bytes specified by the length. Examples: An empty string is encoded as 0:. The string "bencode" is encoded as 7:bencode.
