This entry point is used when the reader has done the reading of the source file, but did not do any processing further. The parameter p points to the ReadObject. The preprocessor at this point can access the lines of the core BASIC program file without the included files and the very first line of the program that may be a Windows NT or UNIX special line (like #!/usr/bin/scriba) is still in the input lines.
The function has to return zero or the error code and should set the parameter *pCmd to PreprocessorContinue, PreprocessorDone, or PreprocessorUnload.
