Working with File Manager
- File Manager overview
- Getting started with File Manager
- Viewing and changing data sets
  To view data stored in a supported data set, use the View Utility or the Edit Utility.
- Creating and editing templates
  For many tasks performed with File Manager, you can manipulate your view of a data set by applying a template.
- Working with the Template List
  Display a list of templates and perform actions on them.
- Filtering records with templates
- Managing data sets
  - Working with data set lists
  - Creating data sets and records
  - Creating, replacing, and adding data using existing data
  - Copying data sets
  - Cloning data sets
    The clone utility provides a convenient way to copy multiple sequential, partitioned, GDG, and VSAM data sets.
  - Finding and changing data in multiple PDS members
    - Building your member list for processing
    - Refining the list of selected members
    - 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.
    - Specifying context in the output listing
    - 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.
- Enhanced ISPF: Reference List, Search, Change, and PDSE Workbench
  File Manager provides several enhancements to the basic facilities that are available in an ISPF session: Enhanced Reference List, Enhanced Search, Enhanced Change, and PDSE Workbench.

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.
