 Color 64 was written to be easily modified.  Several things have been designed into the system to make it easier for the programmer to modify the BBS system:
-The Color 64 ML adds many powerful commands and functions to BASIC's vocabulary, so that code can be designed as efficiently as possible. The ML code supporting this for versions 8.1 and beyond resides at $C000–$C3FF, with the token interception layer being invoked at $0314/$0315.
+The Color 64 ML adds many powerful commands and functions to BASIC's vocabulary, so that code can be designed as efficiently as possible.
 The overlays were designed uniformly, so that all overlays have the same basic "skeleton" of essential routines.
