What information does ADDI capture when analyzing program call chains in a COBOL application?

Think of it like working hands-on with IBM mainframe systems — the answer here is 'The source location and calling program for every static and dynamic CALL statement in the portfolio'. ADDI traces both static and dynamic CALL statements across the portfolio, recording which program calls which and at what source location, enabling full call chain reconstruction for impact analysis. On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.
