Word Wrap Insert Mode - IBM 3270 User Manual

Word wrap is automatically turned on when document mode is
established. A word wrap symbol
(.!.\.)
appears in column 70 of the
operator information area when this capability is operational. Word
wrap is turned on or off when the WRAP key is pressed.
Word wrap obeys margin boundaries. If any character, other than
DUP or space, is entered into the column position immediately left
of the right margin on the current row, then the entire word is
placed on the next row, beginning at the left margin. If the word
occupies that entire row, if the current row is the bottom row, or if
the field in the next line is protected, then input is inhibited and the
Too Much symbol
C)(
*>.)
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 is done to help ensure that the document will remain as the
operator sees it on the screen after it is sent to the host in a
read-modified operation.
A space character entered into the column position immediately left
of the right margin position does not cause word wrap to occur, but
causes the cursor to be positioned at the left margin of the next row.
If
the cursor is in the column position immediately left of the right
margin and the DUP key is pressed, the DUP character is placed in
the right margin, and the DUP function is performed as defined
when not in document mode.
Note: When word wrap is used with the 3180 Modell extended
functions, the window is automatically scrolled when the last line in
the window is filled.
3.2.2 Word Wrap Insert Mode
When a display is in insert mode and word wrap is enabled, a word
pushed out beyond the right margin because of inserted characters
on that row will wrap onto the next tow if that row contains enough
spaces following the last word and/or enough nulls (within the
margins) to accommodate the wrap.
