This function calls the initialization functions of the modules that are statically linked into the interpreter. This is essential to call this fucntion from the embedding main() program in a variation that has one or more external modules staticallyl linked. If this function is not called the module initialization will not be called, because the module is never actually loaded and thus the operating system does not call the DllMain or _init function.
The function has to be called before the first interpreter thread starts. In case of a single thread variation this means that the function has to be called before the BASIC program starts.
The function does not take any argument and does not return any value.
