This entry point is used when the reader has done the reading the source file and unhooked the optional first Windows NT or UNIX start line (like #!/usr/bin/scriba), but did not process the included files. The preprocessor at this point can access the lines of the core BASIC program file without the included files. The parameter p points to the ReadObject.
The function has to return zero or the error code and should set the parameter *pCmd to PreprocessorContinue, PreprocessorDone, or PreprocessorUnload.
