Introduction:

The COBOL copybook import program, DBXRCIN, reuses or versions a copybook in the Repository based on several criteria.  

One of which is the Input dataset name (QUAL_DATASET_1).              

If the same copybook exists in multiple datasets, then this will result in multiple versions of the same copybook stored in the Repository under the COPYBOOK entity type.  

The symptoms of this behavior are that multiple versions of the copybook are present in the Repository under the COPYBOOK entity type which makes it difficult to

perform impact analysis when there are multiple versions.                                             

                                                                          

Instructions:

Currently, the PARMFILE for DBXRCIN contains 24 parms.  A new parameter has been added at the 25 position to control behavior     

of when a copybook should be reused or versioned based on the Input dataset name.  This requires that PTF RO97093 has been applied.                                       

If Parm 25 is provided with a value of 'N' then the input dataset name is not used as a distinguishing factor when attempting to reuse a dataset.

In other words, if the same copybook exists in different datasets and is imported with parm 25 set to N,

then the COPYBOOK entity will not be versioned.            

If the parm is omitted then DBXRCIN behaves as it normally would which would result in multiple versions of the copybook if the input dataset name is different.                                                                  

N    ; 25. DO NOT USE INPUT DATASET AS REUSE CRITERIA?
