A Free Hero Mesh puzzle set consists of four files; this article is about the .class file, which contains the program codes implementing the rules of the game.
This file is a plain text file, with a somewhat Lisp-like format, describing the classes of objects, their attributes, and the code to implement their behaviours; however, the code implementing behaviours is stack-based, like Forth or PostScript. It also includes a macro preprocessor.
The character encoding is normally the PC character encoding (CP437); however, it is possible to declare the use of other IBM PC code pages other than 437 as well (see MS-DOS encodings). The (CodePage) block specifies the number of the code page to use; if it is omitted, then 437 is assumed by default.
