Moving The Cursor To The Beginning Of A Field; New Line Key - IBM 3270 Operator's Manual

want to be able to move the cursor around quickly to correct
any errors you might detect while working.
These keys are divided into two types:
1. Those which move the cursor to the first character location
in a field.
2. Those which move the cursor one character position at a
time.
The New Line key moves the cursor to the first new line on the
screen containing the first unprotected character location in
which you can type. This new cursor location depends on the
existing data displayed and on the screen format.
When the New Line key is pressed, there are five possible new
cursor locations where you may begin entering data.
1. If the screen is unformatted, the cursor is moved to
the
first character position in the next line.
2.
If the screen is formatted, the cursor moves to one of three
locations:
a.
The first character position in the next line,
as shown in
the middle example of Figure
12.
Pressing the New Line
key when the cursor is located at A moves the cursor to
B.
In this case, there is no protected field or character
present at the first character position in the next line;
therefore, the cursor is positioned at the left margin in
the next line.
b.
A character position within the next line,
as shown in
the top example in Figure
12.
I n this case, the cursor is
placed in the first unoccupied location past the pro-
tected field called" Item Description".
c. A character position on the first new line available.
It
may happen that the first new line contains all
protected fields. Therefore, the cursor must keep
searching until some new line is found containing the
first unoccupied character location in an unprotected
field.
3. If all character positions on the screen are protected,
the cursor is repositioned to the first character location
on line 1.
The New Line key is typamatic and will move the cursor
quickly from line to line.
