Display Commands

The command used to display Media Database information on the console depends on the type of records (volume, data set, or group (chain) of volumes) to be displayed.

Just as record information can be displayed in the Inquiry/Update screen using different display types, record information can also be displayed on the console using different "views". A predefined, default view is provided for each record type to be displayed. The INCONTROL administrator can modify these views and define other, optional views.

Format of the display command is:

CTT rectype parms[,v=viewname]

where:

• rectype is the record type indicator. Mandatory. Valid values:
  • DVL Volume record
  • DDS Data set record
  • DVG Group (chain) of volumes
• parms are the parameters identifying the desired record. Mandatory. This includes volser (volume serial number) for all record types, and labelnum (the number of the data set on the volume) for data set records only.
• viewname is the view (format) in which to display the information. Optional. If not specified, the default view is used.

  Valid display commands are shown below:
