Note that the body of Usage must be -- coordinated with the switches that are recognized by this package. -- The Usage package also acts as the official documentation for the -- switches that are recognized. In addition, package Debug documents -- the otherwise undocumented debug switches that are also recognized. package Switch.C is procedure Scan_Front_End_Switches (Switch_Chars : String); -- Procedures to scan out front end switches stored in the given string. -- The first character is known to be a valid switch character, and there -- are no blanks or other switch terminator characters in the string, so -- the entire string should consist of valid switch characters, except that -- an optional terminating NUL character is allowed. A bad switch causes -- a fatal error exit and control does not return. The call also sets -- Usage_Requested to True if a ? switch is encountered. end Switch.C;
