Entry types that can be altered

An "X" in Figure 1 indicates that you can alter the value or attribute for the type of catalog entry that is shown. Some attributes apply only to either the data component or the index component of a cluster or alternate index entry. You can use some attributes only for the data or index component of a cluster or alternate index entry; you must then identify the entryname of the component. Use the LISTCAT command to determine the names generated for the object's components.

You can identify a group of entries with a generic name. Entrynames that match the supplied qualifiers are altered if they have the information that is used with the ALTER command.

You cannot alter alias entries or a master catalog's self-describing entries, nor can you change a fixed-length relative record data set to a variable-length relative record data set, or the reverse. You cannot change a linear data set (LDS) to any other VSAM data set format. Any attempt to alter a data set defined with a device type named by the user (for example, SYSDA) is unsuccessful.

When the data set characteristics being altered are for a compressed data set, the maximum record length of the control interval size is less than if compression is not done.
