Working with Z Data Tools
- Z Data Tools overview
- Getting started with Z Data Tools
- 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 Z Data Tools, 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
- Using Z Data Tools utilities
- Tape Specific Functions
- Disk/VSAM Data Functions
- OAM Functions
- Using UNIX™ System Services and the Hierarchical File System
- Introduction to programming with Z Data Tools functions
- Enhancing Z Data Tools processing
  You can enhance normal processing of a number of Z Data Tools tasks by supplying a procedure that runs in conjunction with the Z Data Tools process.
  - Why enhance Z Data Tools 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 Z Data Tools 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.
    - Coding DFSORT procedure statements
    - Coding REXX procedure statements
    - Coding end of file procedure
    - Combining DFSORT and REXX statements in a procedure

  - How enhanced processing works
  - REXX and DFSORT Examples
  - Examples of tasks that can be performed easily using FASTREXX
- 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
  Z Data Tools provides several enhancements to the basic facilities that are available in an ISPF session: Enhanced Reference List, Enhanced Search, Enhanced Change, and PDSE Workbench.

Supplying a procedure to enhance Z Data Tools processing

How you supply a procedure to enhance Z Data Tools processing depends on whether you are using a Z Data Tools panel, running Z Data Tools in batch, or invoking Z Data Tools from a REXX program.
