When document mode is on, the characters DOC appear in the
operator information area and the Entry Assist functions are
available.

When document mode is off, the Entry Assist functions are

not available and your terminal operates exactly as it
did before.
Let's try setting margins and also see how word wrap
works.
Do the following:
Turn on document mode.
The DOC symbol and an arrow
that points down appear in the operator information area.
This is the word wrap symbol and means that word wrap is on.
Position this line of text at the top of the screen.
(This is to avoid a procedural problem later.)
Press the CHG FMT key.
This puts the display into
change format mode, so you can observe and change line formats.
A scale line appears in the operator information area
(instead of the normal symbols), and an additional cursor
appears on the scale line.
The scale line shows
the current settings of the margins, tab stops, and the
"end of line" signal position.
The symbols used on the scale line are as follows:
margins
< and > symbols
tab stops
_ symbol
end of line signal position
* symbol
Move the cursor so that it lines up with the number
starting this sentence.
Type the < symbol on the scale line.
The previous < symbol
disappears and only the one you typed remains on the scale line.
This is the new left margin.
The scale line cursor
also disappears, but reappears when you press the Cursor Move key.
Move the cursor until it lines up with the last
character on this line, and type the > symbol.
This sets your right margin at that position.
Press the CHG FMT key again.
This takes you out of change format mode.
The scale line disappears, and the cursor returns to
the position it was in when you entered change format mode.
Use the margins you just set.
Hold down the New Line key.
The cursor stays at the new left
margin you just set as it goes down the screen.
