Allocating unload data sets dynamically with UNLOAD PLUS allows you to:

  • Eliminate large, complex DD statements
  • Release unused space when UNLOAD PLUS closes an unloaded data set
  • Use symbolic variables and generation data groups (GDGs) to support data set name generation
  • Reduce JCL maintenance when object definitions change (such as when partitions are added, or a new table is added to a table space)
  • Reduce the manual process of sizing unload data sets by performing automatic size estimation based on object characteristics
  • Leverage your storage management subsystem (SMS) configuration to minimize x37 abends or inadequate space abends
