The PREFIX value must be specified with 25 characters or less. If a PREFIX value is not specified, the library name is used by default. However, if the library name is longer than 25 characters, it cannot be used for the PREFIX parameter. Instead, the PREFIX value must be specified explicitly.
The command is not processed.
Reissue the PERFORM LIBACTION command and specify the PREFIX parameter with a value that contains 25 characters or less.
