IBM 3270 User Guide

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 DUP key, the DUP character Is placed In the right margin, and
the DUP function Is performed as defined when not In document mode.
Note: If 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.
Word Wrap with Insert Mode On
When a display has both insert mode on and word wrap on, a normal Insert
operation occurs whenever there are either ending space characters (see note) or
a null character between the cursor and the right margin. Otherwise, the display
tries to wrap the word to the Input area of the next row.
Word wrap behaves differently depending on whether or not your system Is using
Configuration Support B Release 2. If you are not certain what configuration your
system uses, see your system administrator.
A word wraps to the Input area of the next row only If there are enough ending
nulls or space characters (see note) to accommodate the wrap. On a control unit
prior to Configuration Support B Release 2, word wrap does not occur If there are
any field attributes In the entry area of the next row. On a 3174 with Configuration
Support B Release 2 or later, word wrap occurs whenever there are enough ending
nulls or space characters within the first field of the next row's Input area to
accommodate the wrap.
Space characters appear In the position formerly occupied by the wrapped word. If
the left margin position of the next row did not contain a space character prior to
the wrap, a space character Is wrapped with (or Is appended to) the word being
wrapped In order to preserve word separation.
If there Is not enough room for the wrap to occur. Input Is Inhibited and the Too
Much symbol (X X >) appears In the operator information area.
Note: A space character ('40'x) Immediately preceding the right margin position
Implies that a word has been entered In the right margin area. To maintain
separation of words between the entry area and the right margin, the
character Insert operation does not always allow a graphic character to
overwrite a space character (or to overwrite a null character, If enhanced
null/space processing mode Is active) In the last position of the entry area.
A graphic character In the last position will be overwritten only If the right
margin position contains a field attribute, a null or a space - which serves
as a separator between the entry area and the right margin.
Typematic Move Cursor to Next Word
To move the cursor to the first character of the next word, press the Cursor Right
key In ALT Shift.
if the cursor Is within the last word on a line within margins, the cursor moves to
the first null or blank after that word. The final cursor location must be In an
unprotected field.
Margin limits are not observed In the following circumstances:
