File Format
Name MBASIC tokenized file
Ontology
Extension(s) .bas
Released 1975

MBASIC is the direct descendant of the original Altair BASIC from Microsoft, adapted for the CP/M operating system. The various BASICs descended from that starting point were generically known as BASIC-80, and had varying degrees of similarity.

MBASIC used a similar file format to that of the later GW-BASIC tokenized file, though the token values were different.
