Overview

This oscli(a) function will pass the command line interface (e.g. Unix or MS DOS) command to the operating system for execution.

  • Pass: A String representing the command
  • Returns: Nothing
  • Throws: The error string oscli if the operating system returns an error to this call

Example

#include <io>
#include <system>

function void main() {
   var a:String;
   input(a);
   try {
      oscli(a);
   } catch ("oscli") {
      print("Error in executing command\n");
   };
};

The above program is a simple interface, allowing the user to input a command and then passing this to the OS for execution. The oscli call is wrapped in a try-catch block which will detect when the user has request the run of an errornous command, this explicit error handling is entirely optional.

Since: Version 0.5
