The Learn QuickC command invokes the QuickC tutorial. The tutorial does not affect any files you have already loaded. You can continue editing them when you return to the QuickC environment. If the tutorial cannot be found on your PATH, DOS issues a "Bad command or file name" error. Use the Customize Menu command to change the parameters for the tutorial. You can also use Customize Menu to remove Learn QuickC from the menu if you never use that command. Press CTRL+Q to exit the tutorial at any time and return to the QuickC environment.
