OVERVIEW
1.3 OVERVIEW ____________
It is assumed that the user already has an understanding of
FRESS concepts and facilities (see DOCUMENTATION), although some
features are briefly described in this section.
FRESS is best used for applications in which online display is
long important, or in preparing ____ documents in which all sections
are to be kept together in the same file and are to be accessed
frequently.
The FRESS editor was specifically designed to edit flowing text
as opposed to more rigidly formatted computer programs. It is
Stream Editor stream-oriented as opposed to line-oriented (see _____________
below).
Some commands such as SURROUND and MOVE, apply specifically to
text processing (see Appendix D for lists of commands by type). A
user can easily move a portion of text with one command. In one
command line, the text can be moved anywhere within the 2100
character Editing Buffer. There is also a facility that allows
the user to defer telling FRESS where the text is to be moved, so
he can travel and search for the new location anywhere in that or
another file, and then easily specify it as the destination of the
Deferrals move (see _________ below).
The FRESS editor can pinpoint desired locations and jump
Hypertext through a file in a speedy, logical manner (see _________ below).
Many different files can easily be accessed and edited during the
same editing session, without having to repeatedly leave the
editing environment (see GFILE).
The FRESS Environment ________________________
FRESS is a self-contained environment designed specifically for
text manipulation. It is used for both creating and viewing
files, as well as for formatting text. Because of this, the FRESS
Command Mode Input Mode environment can be either in ____________ or __________.
Command Mode is the initial state when FRESS is invoked. From
Command Mode, files can be manipulated (e.g., created (MFILE),
opened (GFILE), erased (SFILE)). A vast array of other commands
allow the user to enter Input Mode, edit a file, travel through a
file, or perform system tasks. All commands are described in
Section 5.
Input Mode can be entered through various commands. It is
typically used to enter into the file text strings too long to
enter using one of the editing commands. As text is entered, any
formatting codes (see Section 4) are checked, and error messages
are typed as necessary. A modified version of Input Mode, called

OVERVIEW
Swift Input Mode ________________ does not do this verification, but it is faster
should be used anytime Input Mode and less expensive to use -- it _________________________________
would be used ______________. Any formatting errors can always be found later
using FERROR.
FRESS has defined special meanings for several characters.
These may seem confusing at first, but if Section 3 is read
carefully they should not pose much of a problem.
Stream Editor ________________
stream editor The FRESS editor is a _____________, which means the file can
be thought of as consisting of a single indefinitely long
"superline" or "stream" of text, rather than many discrete lines
(as in a conventional program editor). Text appears at the
terminal on consecutive "logical lines," the length of which the
user may select (see SDISPLAY).
Editing Buffer/Display Window ________________________________
As a stream editor, the scope of FRESS editing commands is not
Editing Buffer 2100 limited to just one line. Instead, an ______________ of ____
characters __________ is searched for the first appearance of the desired
"context pattern." After each edit, the system displays a
Display Window portion of the ______________, which is simply the top part of the
Editing Buffer. FRESS will optionally type any portion of the
Display Window after each editing command (see SDISPLAY). It is
also possible to PRINT the entire Display Window (display it at
the terminal), without having to relocate the Editing Buffer
Editing Mode (which requires some overhead). The _____________, which
Display determines when the Editing Buffer is relocated, and the _______
Mode ____, which determines whether the context string around each edit
location will be typed, are described in Section 2 and are set by
SMODE. Both modes can also be temporarily overridden (see Section
2.3.1).
Getting Output _________________
The user can have a file fully formatted and sent to the
high-speed printer or the terminal using FULLPRINT.

The string being edited. It can be specified by just the
characters at its left and right boundaries (see the description
of ellipses in Section 3).
