The Wedge made disk operations in BASIC 2.0 significantly easier by introducing several keyword shortcuts.
The DOS Wedge became somewhat of a de facto standard, with third-party vendors such as Epyx often incorporating identical commands into fastloader cartridges and other Commodore 64 expansion devices.
's Gazette published several type-in variations on the DOS Wedge, including a C128 version in its February 1987 issue (see External links, below).
The original Commodore DOS Wedge was a 1-KB program written in MOS 6502 assembly language.
It resided in the otherwise unused memory block $CC00–$CFFF (52224–53247) and worked by altering BASIC's "CHRGET" subroutine at $0073 (115) so that each character passing by the BASIC interpreter would be checked for wedge commands, and the associated "wedged-in" routines run if needed.
