Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

 
  Use the Read Only command to make the current window
  read-only. Once a window is made read-only, all of the
  editing commands──Undo, Cut, Copy, Paste, and Clear──
  are inactive and text entry is not permitted.
 
  The Read Only command is a toggle that turns the option
  on and off. Whenever the read-only option is on, an "R"
  appears in the status bar at the bottom of the screen
  and a bullet precedes the command in the menu:
 
    ┌─────────────────────┐
    │• Read Only          │
    └─────────────────────┘
