Tailoring the Data Columns z/OS DFSMS Using the Interactive Storage Management Facility SC23-6856-00 |

ISMF allows you to tailor your list to display only the data columns you want, in the order you want. To tailor the list data columns, use the VIEW command. View names and Views in use are unique to the application in which they are defined. Selecting List Display ColumnsThe
VIEW command lets you select and reorder the columns of application
attributes to display on any application list panel by specifying
a sequence of column (tag) numbers. VIEW is available in any ISMF
application with a list. You can use the VIEW command in two ways:
You can name and save a VIEW, select a VIEW, and delete a VIEW on a View Entry Panel. You can save VIEW across ISMF sessions and manage it on the View Entry Panel List of Saved Views. When you invoke the VIEW command, you see the last VIEW that you used for each list. See Using the VIEW Command without Parameters for more information on how to display and use the View Entry Panel. Entering the VIEW CommandThere
are two ways to enter the VIEW command:
Using the VIEW Command without ParametersWhen you enter the VIEW command without parameters on the data set or volume list, ISMF displays the View Entry Panel. On the View Entry Panel, you specify a series of column tags or an asterisk for the VIEW that you want to see. The order in which the tags are entered is the order in which the columns appear on the list panel. If a column tag is not entered, the column will not appear on the list panel. Exception: You cannot specify the LINE OPERATOR (1) and DATA SET NAME (2) columns on the SPECIFY TAGS field because they always appear as the first two columns on a list panel. You can reference column names and their tags on an entry panel, as shown in Figure 1, the Data Set View Entry Panel. Figure 1. The Data
Set View Entry Panel
Enter DOWN on the command line to see page 2 of the Data Set View Entry Panel, as shown in Figure 2. Figure 2. Page 2
of the Data Set View Entry Panel
When the View Entry Panel is first displayed, the SPECIFY TAGS field is primed with an asterisk, indicating that all columns are to display in the ISMF default order. If you enter an asterisk at the end of a sequence of tags, the columns you specify appear in the order you choose followed by all remaining columns in their default order. For example, enter 19 6 8 * in the SPECIFY TAGS field. Press the ENTER key. The list panel displays columns 1, 2, 19, 6, and 8, followed by the remaining columns in the ISMF default order (3, 4, 5, 7, 9,...). The criteria on the View Entry Panel are saved between uses of the command. You can save, select, or
delete views on the View Entry Panel by choosing one of the following
options:
If you specify an option but leave the VIEW NAME field blank or the view you specify does not exist, a List of Saved Views is displayed with saved view names and tag sequence information. Figure 3 shows an example of the List of Saved Views format for the View Entry Panel. Figure 3. Data Set View Entry Panel
List of Saved Views Format
For more details about managing your saved views, refer to the ISMF online help panels. Using the VIEW Command with ParametersUse the VIEW command with parameters to select and reorder thecolumns to appear on your list panel without leaving the list display. The VIEW command can be followed by a series of tags or an asterisk. This causes the list panel to be redisplayed in the order specified by the view criteria. You can enter the VIEW command with the following
optional parameters:
Press the ENTER key after specifying the VIEW command parameters. Without displaying the View Entry Panel first, the list panel displays with the columns appearing in the order specified by your view criteria. When you enter the VIEW command with parameters, ISMF saves the values you specify. The next time you invoke the View Entry Panel with the VIEW command, the panel is primed with these values. The view criteria are saved across ISMF sessions. You
can enter existing line operators and commands for all list panels
with some changes when VIEW is in use:
Error Handling during the Tailoring of a ListISMF uses short and long error messages to document errors in tailoring a data set or volume list. ISMF informs you of errors by displaying a short error message describing the problem. You can still continue working with the displayed list, but the list might contain some entries that do not meet your filter or sort criteria. If the short error message does not give you enough information, use the HELP command to display the long error message. Use the HELP command again to see the message help panel. If an error in sorting or filtering makes it impossible to redisplay the list, ISMF displays the selection entry panel. The panel is primed with the selection criteria you chose when you built the list. If you press the ENTER key, the list you originally created is displayed and you can continue working with it. |
