The following subsections list the functions that are implemented in this module. The source text of this documentation was extracted from the source Documentation embedded in the C source as comment. Treat these subsections more as reference documentation and less tutorial like.

The functions in this file compile a ScriptBasic expression into internal form. The functions are quite general, and do NOT depend on the actual operators that are implemented in the actual version.

This means that you can define extra operators as well as extra built-in functions easily adding entries into tables and need not modify the compiling code.
