Operating in document mode is similar to operating in non-document mode ifthe

in a certain way. For example, ifdefault margins

When using a full-screen editorthat has a line command field,
set

• If
the

• If

Mostofthe
time,
the

When
document

is on
and
tab

are
set,
the

causes

The

that
contains
both

and

produces
a

with
the

the
formatting controls.
You
can
change
the

and
another

When you format a
document
using Entry

formatting controls, you
cannot
reformat
it at a
later
timebychanginganEntry

From
the
DCF
viewpoint.
Entry

•
Helps
you
create
and
edit
the
input

set
•
Provides
limited
formatting
for
margins
and
tabbing.
DCF
requires
that
formatting
commands
appear
in specific
column
locations.
When you
enter
a DCF
document,
you
must
set
the
left margin for Entry

appropriately.
For
example:
•
When
using
EDGAR,
set
the
left

•
When
using

set
the

Application
Hints
Using Entry Assist to Create and Maintain Source Programs
Source programs are typicallymaintained infixedcolumnformat. For example:
NAME
OPERATION
OPERANDS
COMMENTS
To
use
Entry
Assisttocreate
this
format:
1.
Set
the
left
marginatthe
NAME
column.
2.
Set
tab
stopsatthe
OPERATION, OPERAND,
and
COMMENTS
columns.
Nowyou can
enter
source
statements
without thinking about column locations.
If
you need to continue to another line,
set
the "end of line" signal to provide a
warning
of a
line
ending.
To
create
program prologue sections or other
areas
of continuous comments, the
following
techniqueisuseful:
1. Create a group of lines withthe *character in the first and last positions of the
line. (Todo this fast,
use
the duplicate line command [" n] with
XEDiT,
and the
Repeat LineCommand [Rn] with the SPF editor.)
The
formonyour
screen
should
look
like
this:
2.
Set
margins
within
the
pair
of *
characters
as
illustrated
below.
The
Less
Than
character
(<)
represents
a left margin. The
Greater
Than
character
(>)
represents
the
right margin. (Youdo not actually
see
the<and
> symbols
exceptonthe
scale
line
wheninChange

Withword wrap on, you
can
enter
comments
into the lines you

without

functions
yourself.
In using

Entry

provides
functions
that
makeiteasier
to
enter
and
edit
text
material.
You
can
enter
the
same
things
you
enter
now
with
your
editor
program.
Entry
Assist
has
margins,
tabs,
and an
audible
"end
of
line"
signal.
Each
of
these
functions
acts
just
like
the
corresponding
functions
on a
typewriter.
Entry
Assist
has a word wrap
facility,
which
allows
youtotype
without
havingtouse
the
New
Line key.
Word
wrap
automatically
does a new-line
function
for
you
when
you need a
new
line.
Word
wrap picks up any
partially
typed word
and placesiton
the
next
line.
(The next
line
must be empty.)
Entry
Assist
has
functions
that
allow
you
to
delete
a word,
delete
individual
characters
typematically,
move
the
cursor
to
the
next
or
previous
word,
display
the
row and column numberofthe
current
cursor
position,
and
backspace-delete
whenininsert
mode.
Let's
discuss
the
functions
individually,
and you can
learn
about
them by
using
them.
Make
sure
that
the
Entry
Assist
function
is
available
at
your
display.
To do
this,
press
and hold
the
ALT
key while
pressing
the
DOCONOFF
key.
If
your
display
unit
must beinthe
extended
select
state
(3179 and 3180
units
in

theExSel key before you press
the
DOCONOFF
key.
If
Entry

is
available,
DOC
and
an arrow
that
points

appear
near
the
right
side
of
the
operator
information
area.
If
Entry

is
not
available,
do
not
proceed
with
this
tutorial.
Make
sure
your
keyboard
is
labeled
properly.
Five keys
(six
key surfaces) on your keyboard should be labeled
for
Entry
Assist.
If
this
labeling
has not been done, doitnow
before
you proceed.
If
you have made
sure
that
Entry

is
available
at
your

and
the
keyboard has been

appears
in
the

The

shows
the

and
the
"end

These

Remember
the
following
things
about
using
the
Tab
key:
In
some
situations,
the
Tab
key
inserts
space
characters
that
can
change
the
way
your
printed

looks.
When
document

the
Tab

moves
the

When

the
Tab
key
moves
the
cursor
to
the
next
unprotected
field
or
to
the
next
tab
stop,
whichever
comes
first.
If
the
move
is
to a tab
stop,
it
also
replaces
null
characters
with
space
characters
in
the
unprotected
positions
that
the
cursor
passes
over.
This
preserves
the
spacing
between
the
columns
of

when
the

is
sent
to

The

could
be a problem

let's
see
how
the
new
delete
functions
operate.

Use
the
Insert
key
(which
you
are
already
familiar
with)
to
insert
the
word
"last"
into
the
following
sample
sentence.
Insert
it
just
in
front
of
the
word
"time".
After
you
type
the
word
"last",
press
the
Backspace
Delete
key
to
undo
the
insertion.
Every
time
you
press
the
key,
you
delete
the
previous
character
and
back
up
the
cursor
by
one
position.
The
Backspace
Delete
key
has
the
arrow
that
points
left.
You
can
find
it
on
the
top
row
of
the
keyboard
just
above
the
backtab
key.
Remember,
this
function
operates
only
while
insert
mode
is
set.
Sample
Sentence:
This
is
the
time.
We
also
need
to
understand
how
word
wrap
works
when
insert
mode
is
set.
Do
the
following
for
practice:
Turn
on
insert
mode
and
make
sure
that
word
wrap
is
on.
Insert
enough
words
into
the
first
sample
sentence
below
to
force a word
into
the
right
margin
and
see
how
word
wrap
works
in
insert
mode.
The
words
wrap
out
of
the
first
line
into
the
second
line
as
long
as
there
are
sufficient
spaces
or
nulls
on
the
second
line
to
accommodate
them.
When
the
next
line
cannot
accommodate
the
word,
the
keyboard
locks.
Sample
Sentence:
This
is a sentence.
This
is a sample
sentence.
Now
let's
try
the
cursor
position
indicator
function.
Press
the
CURS
PCS
key.
The
current
position
of
the
cursor
is
displayed
in
the
bottom
row
of
the
screen
in
the
form
rr/cc.
The
letters
"rr"
mean
the
number
of
the
row.
The
letters
"cc"
mean
the
number
of
the
column.
The
rr/cc
value
remains displayed
as
long
as
you
hold
down
the
ALT
Shift
key.
Remember
that
line
formats
(margins,
tab
settings,
and
an

setting)
are
remembered
as
long
as
