What of the following is not a sequential processing?

  1. Using a series of GN calls followed by a GNP call

  2. Using unqualified SSA's with GNP

  3. Using qualified SSA's with GU

  4. Using qualified SSA's with GN

  5. Using no SSA's with GNP

C Correct answer
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.
