MSI-Guide will read ANY Norton Guide (.NG File) including CODERUN.NG, 
  however, CODERUN.NG can only be read by MSIG.EXE.  

  You can run  MSIG ? which will give you a help screen with command line
  options.

  The MSI-Guide is VERY easy to use, using only the arrow keys or mouse to
  operate.  The basic operation is this:
  
      Up Arrow:  Go up an option or scroll screen up.
    Down Arrow:  Go down an option or scroll screen down.
   Right Arrow:  Open or select the current entry.
    Left Arrow:  Close the current entry, go back a level.

  MSI-Guide may or may not be "pre-registered" when you receive it.  If you
  get a ShareWARE Sigon Screen stating that it is a 20-Minute DEMO, or it
  is registered to someone other than yourself -(not nice and illegal too!),
  then you MUST register the product with MSI for long-term operation.


  MSI-Guide allows you to Set and Go To up to 10 simultaneous Bookmarks using
  the Function Keys. Bookmarks contains both the Database & Position Data and
  allow you to rapidly switch from one place to another in multiple guides.
