ISPF Line Commands and TSO commands that reference data set names may be “blocked” on
a data set list screen generated by the DSLIST command or option 3.4. This simplifies issuing
commands against multiple, consecutive data sets.
Watch this QuickRef Academy video to learn more
To select a block mark the first data set with // and then use // to complete the block. The
command must follow either the beginning // or ending //, but not both.
Supported commands include:
Line commands (D – Delete, E – Edit, etc),
• REXX or CLIST program execution.
• IDCAMS – LISTCAT, DELETE, etc.
• DFSMSHSM – HDELETE, HRECALL, etc.
