The Distributed FileManager/MVS Data Agent enables workstation users on Windows, OS/2, and AIX® to invoke DataAgent routines. Through DataAgent routines, users can issue TSO/E commands, CLISTS, or Restructured Extended Executor (REXX) execs to access otherwise unsupported z/OS data sets or databases. For example, a DataAgent routine can extract data from z/OS files and databases, for the client to retrieve. DataAgent routines can be user-written, IBM-written, or vendor-written.
