			     ERROR MESSAGES


	We will take this opportunity to provide additional explanations

	on error messages:

	1.  "Badkeyerr - editor error"

	     Cause:
	     Action: Hit another key.

	2.  "Argument must be numeric."

	     Cause:  You provided a non-numeric argument to a function
		     expecting a number.  For example, typing
			<ARG> j <+LINE>
		     would cause the above error message to be displayed
		     since the number of lines must be an integer.

	     Action: Redo the function providing a positive integer as an
		     argument.

	3.  "Argument must be positive."
	     Cause:  You provided a negative number as an argument to a
		     function expecting a positive number.  For example,
		     typing,
			<ARG> -2 <OPEN>
		     would cause the above error message to be displayed
		     since the number of lines to open must be a positive
		     integer.

	     Action: Redo the function providing a positive integer as an
		     argument.

	4.  "Nothing in the PICK buffer."
	     Cause:  You have pressed <PUT> when no lines have been picked.

	     Action: Use <PICK> to identify the lines to <PUT>.

	5.  "Can't put a window there."
	     Cause:  You have placed the cursor in an unacceptable
		     position for window creation.

	     Action: Reposition the cursor correctly (Read <PORT>).

	6.  "Nothing to search for."
	     Cause:  You have pressed a <+SCH> or a <-SCH> without
		     having specified a string to search for.

	     Action: Provide a string as an <ARG> to a <+SCH> or
		     a <-SCH>.

	7.  "Search key not found!"
	     Cause:  The string you specified as an <ARG> to a <+SCH>
		     (1) does not occur, or (2) all occurrences of the
		     string have already been found between the current
		     cursor position and the end of the file.  For a
		     <-SCH> one of the above conditions exist between
		     the current cursor position and the beginning of
		     of the file.

	     Action: No corrective action required.

	8.  "Can't make any more ports."
	     Cause:  You have tried to create more than 10 windows on
		     the screen.  The maximum number permitted is 10.

	     Action: Discontinue window creation.


	9.  "You cannot modify this file."
	     Cause:  You have attempted to alter a file which is write
		     protected.

	     Action: Cease attempts to change the file.


       10.  "Feature not implemented yet."

		     the Editor does not recognize.

	     Action: Try something else.

       11.  "Nothing in the CLOSE buffer."
	     Cause:  You have pressed <ARG><PUT> when no lines have been
		     closed.

	     Action: Use <CLOSE> to remove appropriate lines and repeat
		     the <ARG><PUT>.

       12.  "Margin stuck; move cursor to free."
	     Cause:  You have tried to type past the end of the line in view.

	     Action: Move the cursor or move the window (see <RIGHT>).
