    - Specifying where your results are stored
    - Specifying your processing options
    - Specifying multiple arguments for FIND
    - Using the CHANGE command in the Find/Change Utility
      The CHANGE command operates on the data set or data set members selected in the Find/Change Utility.

    - Changing data with a REXX procedure
  - Working with files or members containing JCL
    When using the DSC or FCH utility with a file that contains JCL and the JCL Source format option has been selected, there are two methods used to maintain integrity.

- Enhancing File Manager processing
  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.
- Redefines criteria
  Redefines criteria can be specified for a field with a REDEFINES clause, or a field that is the target of a REDEFINES clause.

Changing data with a REXX procedure

You can specify an existing REXX procedure, or create a new one, to further enhance the way in which data is searched.

The find/change procedure is an alternative way to specify find and change commands that provides the flexibility of a REXX procedure. For Find/Change Utility, the REXX procedure is mutually exclusive to the primary commands CHANGE, BOUNDS, and CAPS.

However, you can use the FIND primary command to refine the selection list for the procedure. To do this, do not select the procedure until you have produced the list of members to be processed. You can deselect a record by executing an exit DROP statement. The Find/Change Utility report prefixes each record number selected by the REXX procedure with an “S”, each record changed by the REXX procedure with a “C”, and each record added by the REXX procedure with a “+”.

For general information about using REXX procedures with File Manager options, see Enhancing File Manager processing.
