Viewing the List

A data set or volume list may contain more entries and data columns than you can display on one screen. To see all the information contained in a list, use ISMF scrolling commands to move through the list from top to bottom and from side to side.

Scrolling through Data Columns

Use the following commands to control the data columns displayed on the screen:

Command: Meaning
LEFT: Shows data columns that extend to the left of the current screen display.
RIGHT: Shows data columns that extend to the right of the current screen display.
FIND: Locates a data column that is not currently displayed.

When you use the FIND command, ISMF scrolls to that column and positions the column to the right of column 2, which is the column that identifies the data set or volume. For example, if you want to look at the amount of space allocated when extending an individual data set, enter:

  Command ===> find 16

ISMF locates column 16 and positions it next to the data set names in column 2. The LEFT, RIGHT, and FIND commands reposition the data columns but columns 1 and 2 always appear on the left side of the list panel. Scrolling commands do not affect the position of these two columns when you display a list. Figure 1 shows the result.

                USER1.SPFTEMP1.CNTL          -------  338001  NO    3380

If the column you specify with the FIND command is already displayed on the screen, the column is not repositioned. Specifying the parentheses is optional.

Scrolling through List Entries

The following commands control the entries displayed on the screen:

Command: Meaning
UP: Shows list entries that extend above the current screen display.
DOWN: Shows list entries that extend below the current screen display.
TOP: Scrolls to the first page of a list of entries. Using the TOP command is the same as using the UP MAX command.
BOTTOM: Scrolls to the last page of a list of entries. Using the BOTTOM command is the same as using the DOWN MAX command.

Scrolling Amounts

You can specify the following scrolling amounts:

Amount: Meaning
nnnn: A number from 1 to 9999—scrolls the number of list entries or data columns you specify.
PAGE: Scrolls a screen of data, either list entries or data columns.
HALF: Scrolls a half page of list entries or data columns.
MAX: Displays the first or last list entry or data column.
CSR: Positions the list entry pointed to by the cursor at the top, bottom, left or right of the screen.
DATA: Scrolls one entry or one column less than a full page of data. Entering DATA as a scrolling amount is the same as entering PAGE when there is only one data column other than columns 1 and 2 displayed on the screen.

You can abbreviate the PAGE, HALF, MAX, CSR, and DATA amounts by entering the first letter in the scroll field on a panel.

      SCROLL ===> PAGE
Entries 901-914 of 999
Data Columns 16-19 of 42

Enter scrolling amounts in one of the following ways:

Enter the amount in the scroll field. This new scrolling amount remains in effect until you change the amount in the scroll field again.
Exception: Following a MAX scroll, the scroll field reverts to its previous value.
Enter LEFT, RIGHT, UP, or DOWN on the command line followed by the scrolling amount. This results in a one-time override of the scrolling amount.
Enter the scrolling amount on the command line and press a PF key previously set to a scrolling command. This results in a one-time override of the scrolling amount.

Folding the Data Set List

Use the FOLD command to maximize the number of entries or data columns displayed on a single screen.

You can use FOLD only in the Data Set Application. FOLD controls the width of the DATA SET NAME data column on the Data Set List Panel.

Enter FOLD on the command line of the Data Set List Panel. This command lets you toggle between a list in folded mode or unfolded mode. For example, when you enter the FOLD command on a list in folded mode, ISMF redisplays the list in unfolded mode. To see the list in its original mode, enter FOLD again.

When your list is in folded mode, the DATA SET NAME data column is 27 characters wide. If the data set names of your list entries have more than 27 characters, a second screen line is used to accommodate each entry. When your list is in unfolded mode, the DATA SET NAME data column increases to 44 characters. This increase in size lets long data set names fit on a single line instead of two.

Your list in unfolded mode may contain more list entries on a single screen than when it is in folded mode. However, the list in folded mode accommodates more data columns.

Figure 2 shows a data set list in folded mode with the FOLD command specified on the command line. Some of the entries in this list have a data set name that is too long to fit on a single line of the DATA SET NAME data column.

The Data Set List Panel in Figure 2 shows 11 data sets on the screen. This list displays six data columns. After the FOLD command is executed, this list looks like the one shown in Figure 3, which displays all 14 data set entries but only four data columns.
