After you display a data set list by leaving the Option field blank, you can enter a line command to the left of the data set name. You can also enter TSO commands, CLIST names, or REXX exec names. If a '>' is used before the CLIST or REXX exec name, the parameters passed to the command are not translated to upper case. The z/OS® UNIX commands OGET and OPUT can be entered and the parameters are also not translated to upper case.

The slash ( / ) character, which can be used with TSO commands, CLISTs, and REXX EXECs, can also be used with the V (view data set), B (browse data set), D (delete data set), E (edit data set), and M (display member list) line commands to specify a member name or a pattern. You can type over the field containing the data set name to enter commands that require more than the space provided. For more information about using this symbol, see Using the slash ( / ) character. For more information about member name patterns, see the details about Displaying Member Lists in the "ISPF Libraries and Data Sets" topic in the z/OS ISPF User's Guide Vol I.

You can also enter line commands in block command format to execute the same line command for several data sets at once. You mark the block by typing a "//" at the beginning of a block of rows and another "//" at the end of the block of rows. You must type the line command either immediately after the // on the first row of the block, or immediately after the // on the last row of the block. You can enter several blocks of commands at the same time, but you cannot nest them. Single line commands are not allowed within a block command. You can execute all line commands, including TSO commands, Clists and REXX execs as block commands. If you have selected the DSLIST settings option Execute Block Commands for excluded Data Sets, all applicable excluded rows are unexcluded before the block commands are executed.

Line commands that are valid for aliases may be used with any alias data sets that are listed. Uncatalog, delete, and rename commands are not valid for alias data sets. A line command such as 'B' for browse or 'I' for information will display the real name of the data set.

The Data Set List Utility always supports the U (uncatalog) line command for tape data sets. The Data Set List Utility can support additional line commands for data sets stored on tape and other removable media, by calling external commands such as DFSMSrmm. This interface is configured in the ISPF configuration table and enabled by setting the configuration table keyword DSLIST_RM_ENABLED to YES.

For more information about configuring the Data Set List Utility removable media interface, see z/OS ISPF Planning and Customizing.

If a CLIST, REXX exec, or program is issued against a data set, ISPF gathers information on the data set and makes it available through dialog variables. See Table 1 for the list of those variables. If the data set being processed is on an unmounted file system, a temporary mount is issued, file system.

The Command field and the field containing the data set name fields make up a single point-and-shoot field. If you enter a slash in the Command field or if you select any part of the combined point-and-shoot field, the Data Set List Actions pop-up shown in Figure 1 is displayed so that you can select the command you want to use.
