Dynamic Array Support for copybook overlay

Several of our IMS database segments use dynamic arrays (number of elements imbedded into the structure). We need the capability of modeling these into the E4D tooling to access the data in those arrays.

    Thank you for your interest in keeping IMS a vital and successful product. Software development has continuously evolved during IMS's lifetime, and so has IMS itself. We have kept pace with, adopted, and implemented many industry standard best practices within our organization, including Continuous Delivery, Design Thinking, and Agile.

    At this time, after further review this request for enhancement, we have decided to reject it. The reason we are rejecting RFE ID 83124 is because given our current priorities we cannot in good faith to provide this function in the E4D tooling within 18 months from the date that it is being opened. You are welcome to resubmit this RFE at a later date and we will reconsider.

    In addition, we have recently delivered some enhancements in the JDBC driver recently that allows you to programmatically relieve the dynamic array processing.

    The enhancement allows returning array element data for a fixed array that is partially defined within a variable length segment area. Previously if all elements of a fixed array were not available within a variable length segment area then the array would return null. It is now possible to retrieve paritial array elements that exist within the variable length segment. For example, a variable length segment that has a minimum of 50 bytes and maximum of 100 bytes that has an array of 5 elements that starts at offset 50, each being 10 bytes in length, would be able to return 1 to 5 array elements depending on the variable area. If you have a variable area of 80, you will receive 3 array elements.

    The enhancement described above has been delivered via IMS service process. The APARs offered the support are:
    IMS 14 Java APAR [PTF] PH03415 [UI59326]
    IMS 15 Java APAR [PTF] PH03426 [UI59320]

    If you have any further question about the enhancement, feel free to contact us.

    Have a great day!
