How does Resolve/C++ support command line processing?
A29: RESOLVE_Foundation includes a Command_Line_Handler component that enables you to inspect and process arguments from the command line. In order to use the component in an application program, the procedure “main” must be supplied with a special keyword parameter called end_user_command_line. To process the command line, declare an object of type Command_Line_Handler and then initialize it by calling Get_Command_Line (command_line_arguments). This procedure uses the special keyword parameter command_line_arguments to convert the command line into (what amounts to) a Sequence of Text. The function Number_Of_Arguments() can be used to find out the length of the Sequence, which is indexed from 0 to Number_Of_Arguments() – 1. Note that Number_Of_Arguments() counts the name of the executable as an argument, so its value will always be at least 1. You can process the arguments with any of the Text operations by using the accessor operator [i], whose value is the ith argument from the orig
