DISPLAY DSN

The DISPLAY DSN command displays data set and extent information for data sets that are selected according to the specified filter.

Data set masks are specified according to the rules for masking within the group definition statement. A ’**’ matches any character string through any number of data set name qualifiers. A ’*’ matches any character string within a single qualifier. If the filter is omitted, all data sets are displayed.

Syntax: DISPLAY DSN [groupname | ccuu | dsn-mask]

Example: D DSN 695

Along with the source data set name, group name, and the temporary target data set name, two lines are formatted for the following:

Each data set extent that shows the source and target devices (CCUU and volser)
Source and target cylinder and head (CCHH) locations
Status, number of tracks, percent complete, and the CCHHR of the source and target DSCBs within their respective VTOCs.

Note: The DISPLAY DSN command only shows the data set and extent information after the specified group is activated for the first time. Before that, the control blocks that drive the display have not been built.
