A programme for COBOL developers who write applications against IMS hierarchical databases. It covers the IMS database model, PCB and SSA structures, DL/I calls, status codes, batch and online access and debugging. Labs build working programs that read and update IMS data, as in many long-running banking and insurance systems.
