The IMS™ Information display provides:

  • General information about the IMS™ region
  • Last DL/I call parameter list
  • Information about all PCBs

    All PCBs are shown in the order of their relative PCB number with identification of current (or most recently used) PCBs.

    If available, JCB call trace information follows each data base PCB, showing the most recent call and up to five previous calls.

  • IMS™ accounting information
  • The address of the DFSPRPX0 parameter module

    Selecting the address point-and-shoot field permits you to view the module storage in hex-dump format.

By default, the IMS™ Information display is shown in the Detail format. In this format, all PCBs are shown fully expanded. By instead selecting the Summary point-and-shoot field from the display header, PCBs are instead provided condensed in a table format, as in the example shown in Figure 5.
