    ****************************************************************
    The QRPL, embedded in the BLOA, changed size between V701 and
    V710. This causes some of the offsets used in end of task
    processing to be different between a V701 BLOA and a V710 BLOA.
    The V701 code only checks for V701 offsets, causing it to use
    the wrong fields in the V710 BLOA for the STORAGE release
    request.

Comments

  • The code was changed to correctly detect a BLOA created by an
    adapter at V710 or higher and use the correct offsets.
