Using the Cursor Movement and Editing Keys
This section expiains how to move the cursor and use the editing keys.
The following functions, which provide fiexibiilty during text entry and edit oper
ations, are available in document mode.
Using Word Wrap
To turn word wrap on or off, press the WRAP key.
Word wrap is a function that automaticaliy moves the iast word on a row to the next
row if the word would otherwise overrun the right margin.
Wordwrap is automatically turned on when document mode Is established. A
word wrap symbol
(^) appears in column 70 ofthe operator information area
when word wrap is operational.
Word Wrap with Insert Mode Off
When a display has insert mode offand word wrap on, a wrap can occur only ifthe
entire entry area of the next row contains nulls and spaces.
Youcan wrap a word of any length less than the total space between the margins
(exclusive ofthe margins). Space characters are placed inthe position formerly
occupied by the wrapped word.
Word wrap obeys margin boundaries. If you enter any character, other than DUP
or space, into the column position immediately left of the right margin on the
current row, the entire word is placed on the next row, beginning at the left margin.
If the word occupies that entire row, ifthe current row is the bottom row, or ifthe
field in the next line is protected, then input is inhibited and the Too Much symbol
(X X >) is displayed in the operator information area.
If the left margin is within an unprotected field on the screen, nulls to the left of the
left margin within that field are changed to spaces. This makes the document look
just like you see it on the screen after you send it to the host in a read-modified
operation.
If you enter a space character into the column position immediately left of the right
margin position, word wrap
does not occur. The cursor moves to the left margin of
the next row.
If the cursor is in the column position immediately to the left of the right margin
and you press the DUPkey, the DUP character is placed in the right margin, and
the DUP function is performed as defined when not in document mode.
Note: When you use word wrap with the 3180 Model 1 extended functions, the
window is automatically scrolled when the last line in the window is filled.
