APPENDIX A.  TEXT EDITOR

Nova-Text is a utility for creating and editing textfiles (sequential
files). Nova-Text provides a number of editing functions accessible
with control key combinations. A list of editor commands is available
on a single help screen from within the program by pressing CTRL-H.

Nova-Text uses as much contiguous internal memory as possible for
editing textfiles. This means that you may edit textfiles up to about
38K in size (about 39,000 bytes, or 150 disk blocks).

A.1  Status line

Nova-Text uses a status liine at the top of the screen to indicate various
settings. From left to right, you'll see the following information:

1. Current line and column position of the cursor. L indicates th
line number and C indicates the column number.

2.  A flag indicating insert (Ins) or overwrite (Ovr) mode. In insert
mode, any text you type is always inserted before the text under
the cursor. In overwrite mode, text under the cursor is overwritten
by your typing.

3.  The current disk device and drive/partition number. If the current
device is set to the buffer, the word Buf appears here.

4.  The name of the file being edited, if there is one.

5.  An asterisk next to the file name indicates the current file has been
modified.

A.2  Loading a file

To load a file into the editor, press CTRL-L. Type in the name of the
file.

A.3  Entering text

To enter text in the editor, simply start typing. To move the cursor
around, use the arrow keys. Additional navigational commands are
provided:

F1:  Page up - moves up a page.
F2:  Top of file - moves the cursor to line 1.
F3:  Page down - moves down a page.
F4:  Bottom of file - moves the cursor to the last line.
F5:  End of line - moves the cursor to the end of the current line.
