PH67608: IN RSEAPI 1.2.2, WHEN PERFORMING A SEARCH ON SOME DATASETS, QUERY RESULT FAILS WITH ERROR: DSN(), UNSUPPORTED TYPE UNAVAILABLE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• With RSEAPI 1.2.2, when a dataset search is performed, the
  attributes defined for the dataset are returned, but, with two
  blank lines in the listing.
  
  These lines cause the parsing to fail and the error
  "dsn(dataset name), unsupported type Unavailable" is returned.
  The dataset does have attributes defined, but the RSEAPI code is
  not parsing them correctly.
  
  This is an example:

  * PROBLEM DESCRIPTION: Rmvs list for data sets with name       *
  *                      having SYS. prefix may result in error  *
  *                      "type not supported"                    *
  ****************************************************************
  RSEAPI parsing chokes on "SYS." prefix as it collides with an
  internal marker.
  

Problem conclusion

• Special handling is introduce for parsing correctly.
