AnswerClick to flip back
A
Using qualified SSA's with GU
💡 Explanation:
Sequential processing in IMS navigates segments in hierarchical order. GN (Get Next) and GNP (Get Next within Parent) are inherently sequential. Using no SSA's or unqualified SSA's maintains sequential flow. However, qualified SSA's with GU (Get Unique) performs direct, non-sequential access to a specific segment based on the qualification criteria. Therefore, option C is NOT sequential processing.
