Error description

  • The problem occurs when DFSORT uses BSAM for SORTOUT.
    There is an defect in DFSORT's code that prevents DFSORT
    from using more than 1MB for SORTOUT buffers even when
    there is ample main storage and IOMAXBF is not restricting
    the buffer storage.
    
    
    ADDITIONAL KEYWORDS:
    ACCESS METHOD BASIC SEQUENTIAL ODMAXBF
