Hi,

Can some one please help me with the following concepts...
How IMS executes a GN or a GNP call. How does it maintain a position on Db segment occurence when it executes a GN / GNP ?

Also, I am not clear how a qualified GN / GNP call is better (if so) or atleast different over an unqualified call? Do we have a difference in the return codes (GK is returned for unqualified calls when GN / GNP moves to a different segment on the same level whereas qualified calls will return GE...Please correct me if I am wrong)

Best Regards...
Raman

GN - GET NEXT segment here IMS doesnt holds the parentage

GNP - GET NEXT within Parent, IMS holds parentage and then it does GET next segment under the parent

In GNP - You can expect GK return code,
In GN with Qual or Unqual SSA- You cannot expect GK but it's always GB End of Database

In GU - It's GE status code
