- :: (Line numbers change with the editing process,
- the first line in the file is numbered 1,
- the next, 2, etc.)
-

- ::
- DELETE takes a single line number and deletes that line from
- the edit buffer.
-
- DELETES deletes several lines. How many is specified by the
- top of stack. The location by the next to top.
-
-
- FINISH is used to end the edit session. It appends both
- the contents of the editbuffer to the file
- specified in the last OPENW and the remaining
- lines of the file specified by the last OPENR.
-
- INPUT takes the line number on the top of stack and allows
- the user to enter (insert above the old line specified)
- as many new lines as desired. Completion of input is
- signified by supplying an empty line (an immediate
- carriage return).
-
- LI lists portions of the edit buffer; it acts differently
- depending upon the number of arguments on stack. If
- there are no arguments, everthing is listed (LISTALL).
- If there is a single line number on the stack, that
- single line is displayed.
- Listing a sequence of lines within the edit
- buffer is achieved with two line numbers on the stack.
- The sequence of displayed lines begins with the line
- numbered by the bottom of stack. If the top of stack
- contains a larger number, that number is the number
- of the last line in the displayed sequence. Otherwise,
- if it is a smaller number, it is used to specify the
- total number of lines in the sequence.
-
- LISTALL lists the complete contents in the edit buffer.
-
- NEWF "Newfile" resets all pointers so that anything that
- may have been in the editbuffer is lost. Should be
- used at the start of editing a new task.
-
- OPENR takes a string pointed to by the top of stack and
- opens that named file for reading. It is the user's
- responsibility to make sure that the named file
- exists already. If another file was opened for reading
- previously, it is closed by this new OPENR.
-
- OPENW takes a string pointed to by the top of stack and
- opens that named file for writing.
- (*** It will DESTROY any file that already exists
- with that name!!!****)
-
- READ takes the number of lines specified by the top of
- stack from the file specified by the last OPENR and
- appends them to the end of text in the edit buffer.
-
- REPLACE Deletes the line specified by the top of stack and
- begins INPUT at that same line.
-
- WRITE takes the number of lines specified by the top of
- stack from the beginning of the text in the edit
- buffer and places them at the end of the file
- specified in the last OPENW.
