Uncatalog data set (U)
The Uncatalog data set option (U) uncatalogs a data set from either the system catalog, or a catalog specified in the Catalog name field on the Dataset Utility screen (Dataset Utility screen).
Enter a U in the OPTION field and a valid data set name in the Dataset name field of the Dataset Utility screen to uncatalog the data set. Specifying the Dataset name with pattern characters displays a list of data sets from which to choose.
Press Enter to uncatalog the data set, or use the END command (PF3) to cancel the process and keep the data set cataloged. When the process is completed, File-AID displays the message: DATASET UNCATALOGED in the upper-right corner of the Dataset Utility screen.
