You enter split-screen mode by using the SPLIT command. You also
use this command to reposition the horizontal line that separates
the two logical screens on a 3270 display. On a 3270 display the location
of the cursor identifies the active logical screen. On a 3270 display,
the horizontal divider line that separates the logical screens is
not considered part of either logical screen. If the cursor is placed
on this horizontal divider line and a function key is pressed, the
result is the same as if the ENTER key was pressed and the cursor
is positioned on the active logical screen's command line. Because
ISPF runs in both host and GUI modes, the SPLIT command behaves differently
in each.
- SPLIT command without parameters, in 3270 mode
- If only one screen is currently being used, the physical display
is divided into two logical screens with a divider at the cursor.
If two or more screens exist, the divider line is moved, but no new
screen is started.
- SPLIT command without parameters, in GUI mode
- A new logical screen is added each time the command is given,
until the maximum number is reached. After the limit is reached, a
message appears when the command is issued again.
- SPLIT NEW command, in 3270 mode
- A new logical screen is added each time the command is given,
until the maximum number is reached. After the limit is reached, a
message appears when the command is issued again. Each new logical
screen is added below the cursor, where the split line appears. If
two or more screens already exist, the new one replaces the screen
in which the SPLIT command was not entered.
- SPLIT NEW command, in GUI mode
- This command behaves the same as the SPLIT command without parameters.
End split-screen mode by ending the application on all but one
logical screen. The remaining logical screen is then expanded to the
full size of the display screen.
