Understanding the Format and Contents of the Lists

The output generated from the selection entry panels is displayed in a list panel. A list panel displays information about your data sets, volumes, or SMS classes in tabular form. The first column is a line operator column. The other columns of information are data columns. Each of these columns has a heading (often an abbreviated form of the name) and a number to identify it.

Format of the List Panels

Figure 1 shows the format of a typical ISMF list panel.

Every list panel contains five standard elements: a fixed area, a warning line, data column headings, the list area, and one or two instruction lines.

[1] Fixed Area

Information in the fixed area helps you keep track of your location in the list and how you are navigating through the list.

The fixed area contains the following elements:

The panel title.
A short message area, which appears in the upper right corner of the screen when ISMF detects an error.
The command line.
A scroll field, which shows how far the list entries shift each time you use a scrolling command.
A long message area, which appears when you use the HELP command to further explain a short error message.
An entries statement, which shows how many entries are in the list and which ones are currently on display.
A data columns statement, which shows how many data columns appear in the list panel and the numbers of the data columns currently displayed. Use the LEFT and RIGHT commands to look at columns that extend to the left or right of the columns displayed. The data columns statement is overlaid with a View in Use statement if selected data columns are being displayed.
A directional line (ENTER LINE OPERATORS BELOW).

[2] Warning Line

The warning line is just above the data column headings. This line indicates any special processing conditions that are in effect. Examples are a list filtered by the FILTER command or a list with entries hidden by the HIDE line operator. Filtering the List explains the FILTER command. Using the HIDE Line Operator explains the HIDE line operator.

[3] Data Column Headings

The data column headings identify the type of information presented in a particular column of the list. When using ISMF commands, use the number beneath the heading to reference the individual data columns. For example, to reference the VOLUME SERIAL field on the data set list in Figure 1, specify the column tag 17.

Both data set and volume lists have more columns than can be displayed at one time. The data columns statement in the fixed area identifies the subset of data columns currently displayed. Viewing the List describes the commands used to scroll through all the data columns.

[4] List Area

The list area contains:

The LINE OPERATOR column (column 1), where you enter line operators to do storage management tasks against individual data sets or volumes. This column is always displayed on the panel.
The object name column (column 2), which may be called data set name, volume serial number, or some SMS class name depending on the application you are using. The particular objects that you are working with are listed here. For example, the DATA SET NAME column lists the data sets that you are working with. This column is always displayed on the panel.
The informational columns (the columns to the right of column 2), which describe the data sets or volumes. Viewing the List describes the commands used to scroll through all the data columns.
The BOTTOM OF DATA line, which follows the last entry in the list.

Contents of the List Panels

The data columns represent the different categories of information ISMF can gather for the entries in a list. Table 1 shows the data columns included in data set and volume lists.

The attributes SYSTEM1 through SYSTEM8 of the DASD Volume Application represent the system name or system group name defined in the active CDS. If there are fewer than eight systems defined, the heading RESERVED appears for the unused data columns.

The format used by ISMF to display attribute values might differ from the one used by other products. For example, a fragmentation index of 90 in ISMF is displayed as .090 by DFSMSdss.
