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.
  - Template types and structure
    A Z Data Tools template is a collection of information that you can use to select and format records and fields in an application data set.
  - Template repository
    The template repository is a VSAM KSDS file that is used to associate a data set or resource name with its corresponding template.
  - Managing templates
  - Manipulating the display of fields in records
  - Managing templates with the Template Workbench
  - Specifying scrambling options
  - Mapping fields between templates
  - Copybook View and Print Utility
    Use the Copybook View and Print Utility to view or print field definition information.
  - XML templates
    A Z Data Tools template can be exported to an external XML format using the Template Export utility.
- 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.
- 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.
- Z Data Tools Service Provider for z/OS® Connect Enterprise Edition
  Z Data Tools Service Provider for IBM® z/OS® Connect Enterprise Edition enables client applications to access IBM Z data sources using z/OS Connect.

Selecting your compiler language

To select your compiler language:

From the Primary Option Menu panel, select 0 Settings, then 5 Compiler, and 1 LANG.
Specify your choice by entering the option number:

1. COBOL

Use the COBOL compiler, regardless of the language used in your copybook.

2. PL/I

Use the PL/I compiler, regardless of the language used in your copybook.

3. Auto detect

Note: Applies to COBOL and PL/I only. To instruct Z Data Tools to use the HLASM compiler, yuo must select 4. HLASM.
Allow Z Data Tools to detect whether the language used in you copybook is COBOL or PL/I and select the appropriate compiler.

If the copybook does not contain any keywords that Z Data Tools can use to determine the language, then Z Data Tools uses the COBOL compiler.

If the compiler creates ADATA and produces a return code of less than or equal to the Maximum Return Code specified in the compiler processing options, then Z Data Tools creates the template without any prompting.

If the compiler creates ADATA but produces a return code greater than the specified maximum, then Z Data Tools displays a pop-up menu where you can choose from various options, including using the other compiler.

If no ADATA was created, then Z Data Tools uses the other compiler without prompting.

If the other compiler creates ADATA but the return code is greater than the specified, then Z Data Tools displays the pop-up menu.

If the other compiler does not create ADATA, then Z Data Tools retries the first compiler, and again displays the pop-up menu.

4. HLASM

Use the HLASM compiler.
