What happens if the data on an edit panel or a list of items is too long to fit on one screen? For example, the list of names on the following panel extends below the bottom of the screen.
                            NAMES - LIST OF NAMES
COMMAND ===>                                                  SCROLL ===> PAGE

To view, V, modify, M, delete, D, a name, or copy, C, to the
master directory, type the letter to the left of the selected name.
To add a name, type A on the COMMAND line.
">" beside a name indicates that it is in your private directory.

When a list is longer than one screen length, you can do something called scrolling. Scrolling treats information as if it were on a scroll that can be moved up and down behind the screen. You generally press PF keys to move the information.

Scrolling involves a scroll direction and a scroll amount. The four scroll directions are the same as commands you can type and typically are assigned to PF keys.
Command
PF Key
DOWN
PF 8
UP
PF 7
LEFT
PF 10
RIGHT
PF 11
You can indicate a scroll amount in the upper right hand corner of scrollable panels. There you see a field marked:
SCROLL ===>
The possible values for the scroll field are:
  • A number from 1-9999, representing the number of lines or columns to be scrolled.
  • Page or p, indicating that a full page (screen) is to be scrolled.
  • Half or h, indicating that a half-page is to be scrolled.
  • Csr or c, indicating that the screen is to be scrolled to the line on which you see the cursor.
  • Max or m, indicating that the panel is to be scrolled the maximum amount to the beginning or the end of the information. After max or m is used, the scroll value reverts to its previous value.
  • Data or d, indicating that the panel is to be scrolled a full page, minus one line.

You might notice that all scroll amounts, except for max, stay in the SCROLL field until you change them.
