If PCBs are passed as pointers, it is not supported in our PL1 compiler.

When clients want to see the relationship btw PL1 and IMSDB, it cannot shown. Since if PCBs are passed as pointers, it is not supported in our PL1 compiler.

Background: In our client's current PL/I program, Program Communication Blocks (PCBs) are passed as pointers to facilitate interaction with the IMS Database (IMS DB). However, our PL/I compiler does not support passing PCBs as pointers. As a result, when the client attempts to visualize the relationship between their PL/I program and IMS DB in ADDI, the relationship cannot be displayed.

Issue: When PCBs are passed as pointers in PL/I, this scenario is not supported by our PL/I compiler. Therefore, IMS DB structures and relationships are not visible in the ADDI tool.

Client's Requirement: Our client insists on using PCB pointers in their PL/I programs and is not willing to modify their codebase to work around this limitation. They expect to view IMS DB relationships and program interactions seamlessly in ADDI, which requires support for passing PCBs as pointers.

Question: Given that our client is not willing to modify their existing code and insists on using PCB pointers, what is the best approach for ensuring compatibility with their current setup in ADDI? Specifically, how can we support the use of PCB pointers in PL/I programs without requiring the client to make code changes, while also enabling IMS DB relationships to be displayed correctly in the ADDI call graph?
