-'''Commodore BASIC tokenized files''' stored programs in the versions of the [[BASIC]] programming language used on Commodore computers, including the PET, VIC-20, Commodore 64, and Commodore 128. A number of versions were used, deriving from a version that was licensed perpetually from Microsoft by Commodore for a one-time fee, and further developed internally at Commodore. The most common version is 2.0, which was found on the Commodore 64, though earlier PET computers had BASIC 4.0 (Commodore put an out-of-date BASIC in the 64 because it was "just a home computer" not expected to be used for serious stuff). The Commodore 128 had BASIC 7.0.

The Commodore 128 had BASIC 7.0, and the Commodore 16 (PAL) had BASIC 3.5.
 Like most BASICs of its era, Commodore BASIC used a tokenized format to save its programs, rather than plain-text source code. Printable [[PETSCII]] characters (and the various control codes which could be used within literal strings to do things like change the color of text) generally stood for themselves, but other bytes had different meanings. The "high-bit" bytes from #128-#254 stood for the various BASIC commands and mathematical operators (#255 was used for the "pi" character). A null (#0) byte marked the end of a program line, and some header bytes were used at the start of the line to encode the line number and the byte offset to the next line (a 2-byte [[Endianness|little-endian]] unsigned integer, with 0 indicating the last line of the program).
