{{DISPLAYTITLE:Programming Features}}

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 overlays were designed uniformly, so that all overlays have the same basic "skeleton" of essential routines.   

The overlays were left "open ended", which means that you can easily install one of the many pre-written modules into your overlays. 


<strong>The Enhanced BASIC Language  </strong>

Color 64 offers a set of powerful new additions to the BASIC programming language.  These additions only work while the BBS program is running, as it is a modification of BASIC made by the ML associated with the BBS program.  

The descriptions of the new commands are presented in the following format:  Items enclosed in angle brackets, "<" and ">", are descriptions of data items that you must provide.  Items enclosed in square brackets, "[" and “]", are optional items.
