 Your terminal has special keys that allow you to recall and edit
 previous commands.  These keys are described below.  Note that some 
 of these keys may not be available on your keyboard.
 
 Recalling Commands
 ------------------
 The system saves and allows you to access up to 254 of your most
 recently  entered commands.   The size of the recall buffer is 4Kb,
 which will store approximately 80 commands at 48 characters each. If
 the length of stored commands makes it necessary, one or more of the
 oldest commands will be removed from the recall buffer to make room for
 the most recent command.

 Use the up arrow or Ctrl/B keys to recall previously entered commands.
 Use the down arrow key to reexamine a command that you had retrieved 
 using up arrow.

 If you are supplying commands or data to a program or utility, the 
 system saves and allows you to access only your single most recently
 entered command.


 Editing Commands
 ----------------
 To enable the editing keys, enter the following command:

        SET TERMINAL/LINE_EDITING

 You can add the /OVERSTRIKE or /INSERT qualifiers to the command to
 specify the default editing mode that you prefer.  The /OVERSTRIKE
 qualifier causes a character that you type to be written over the
 character that the cursor is currently pointing at.  The /INSERT
 qualifier causes the character to be inserted before the cursor.
