  You can enhance normal processing of a number of File Manager tasks by supplying a procedure that runs in conjunction with the File Manager process.
  - Why enhance File Manager processing?
    Enhanced processing allows end users to easily perform tasks that would otherwise need to be done by skilled application programmers, and to concentrate on business results rather than data processing problems.
  - Which tasks can be enhanced
    You can supply a procedure with DFSORT or REXX statements to enhance normal File Manager processing according to your own requirements.
  - Choosing the right function to enhance
    With enhanced processing it can be unclear which function or panel to invoke for a particular task, and what combination of template, DFSORT and REXX (or FASTREXX) processing is best to use.
  - Creating and supplying a procedure
    - Procedure statement types
    - Choosing between FASTREXX, REXX, and DFSORT for your procedure
      In general, FASTREXX is the best compromise between performance and function.
