Does anybody know how to block IST664Is where the ALIAS DLU= variable
     is equal to a given pattern ?

     The problem is that the IST664I is a part of a group of messages that
     start with IST663I.

     For example:
     IST663I  CDINIT     REQUEST FROM SSACD001 FAILED  , SENSE=087D0001
     IST664I  REAL  OLU=USSSAN01.CIPCMP5    ALIAS DLU=USSSAN01.HEF61AE0
     IST889I  SID = EB1775A25BA42724
     IST314I  END

     So I want to block IST664Is that have an ALIAS DLU equal to USSSAN01.H
     I don't want to block all IST663Is or all IST664Is.

     Thanks
