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
    - Copying without a template
      When you are copying data sets and do not use a template, all data in an input data set record is copied to the output data set.
    - Renaming members as you copy
    - Copying with a copybook or template
    - Scrambling data
      Scrambling data allows you to create test data based on production (or "live") data, but with the ability to change the values of certain fields. In this way, you can avoid sensitive or confidential information appearing in test data.
    - Copying records with segmented data templates
    - Generating data in external format - XML representation
    - Copying files or members containing JCL
    - Using a DFSORT or REXX procedure
    - REXX member selection
  - 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
  - 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.

  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.

Using a DFSORT or REXX procedure

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

You can code any number of DFSORT or REXX statements and functions to manipulate the output record, select specific records, print reports and tally numeric values.

When you are coding a REXX procedure, be aware of the following:

A copy procedure is run after record-level selection, and any field selection supplied in a template, has been performed.
If the record has been reformatted as a result of the template processing, the variable INREC contains the input record value and the variable OUTREC contains the reformatted output record.
If a Copy count is specified, this can affect the number of records presented to the REXX procedure. The Copy count only applies to the number of records written to the primary output data set. It does not apply to records written in the REXX procedure with the WRITE() function.
When using the PRINT() function with field formatting (TABL or SNGL), the template is determined as follows:
- If an input template without an output template has been specified, the input template is used.
- If an output template is specified, and the record value specified to print is the input record, the input template is used. Otherwise the output template is used.
- If a record cannot be matched against a record layout in the selected printing template, it is not printed.
Ensure the record value matches the template that File Manager uses to print the data set.
