This is the main program of the compiler. It initializes some data, reads configuration file, processes command line parameters, loads library (reports error if it is not found), initializes module data, checks for the main file, resets compilation timer, compiles the source file and writes compilation status.

This procedure processes command line parameters and sets compiler flags and data accordingly.

When no source file is specified this procedure simply displays Turbo Pascal command line syntax with default switch states.
