  ****************************************************************
  A new value for the SERVICE option has been added to HLASM to
  only be used when directed to do so by IBM support.
  When performing a very large assembly a customer experienced
  missing RLD entries on a few occasions. The new SERVICE option
  will enable IBM support to gather diagnostics to determine
  the cause of the problem.
  Customers experiencing possible lost RLDs should contact IBM
  support for advice before attempting to use the new option.
  

Problem conclusion

Temporary fix

Comments

• HLASM has been modified to introduce a new value for the
  SERVICE option which is only to be used as directed by IBM
  support. This new option will enable diagnostic information to
  be saved in the event of lost RLD entries. The diagnostics can
  then be passed to IBM support for investigation.
