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
4 -- Section 1.3anual Release 9.1
