A DSND pointed to by either the ALTICTGN (for an ALTER request) or the GETICTGN (for a GETATTR request) specified a length in the first halfword that was longer than the maximum data set name length allowed, which is 44 bytes.
The first 44 bytes of the data set name will be displayed in the message. Processing of the current invocation is ended.
Verify that the pointer to the catalog DSND points to a DSND beginning with a halfword containing a value up to 44 bytes.
