Summary of changes
Using Z Abend Investigator
Z Abend Investigator installation and administration
- Migrating from an earlier version of Z Abend Investigator
- Preparing to customize Z Abend Investigator
- Customizing the operating environment for Z Abend Investigator
- Using the Z Abend Investigator HFZS subsystem
  Z Abend Investigator uses a subsystem known as HFZS for services that can otherwise not be performed or which might cause incomplete analysis if not started.
- Modifying your ISPF environment
- Customize Z Abend Investigator by using USERMODs
- Customize Z Abend Investigator by using an HFZOPTLM configuration-options module
- Setting up history files
  Z Abend Investigator requires at least one PDS or PDSE data set to be allocated as a fault history file.
- Setting and changing default options for the site
- Providing compiler listings or Z Abend Investigator side files
  - COBOL Report Writer Precompiler
  - Required compiler options for HFZLANGX
  - Naming compiler listings or side files
    Store compiler listings or side files in sequential data sets, or as members of PDS or PDSE data sets.
  - Creating side files with the HFZLANGX utility
    The HFZLANGX utility program converts a compiler listing or SYSADATA file to a LANGX side file.
  - Formatting side files with the HFZLANGP utility
    The HFZLANGP utility can create a readable listing from a LANGX side file, from a SYSDEBUG side file, or from the DWARF debugging information in a program object. This utility can be useful if your installation conserves DASD space by keeping side files rather than compiler listings. The output from the utility resembles the original compiler listing.
  - Naming CSECTs for Z Abend Investigator
    To facilitate source code information, Z Abend Investigator must be able to match CSECT names with the compiler listings or side files provided.
  - Locating compiler listings or side files
  - Compiler listings and side file access requirements
    Compiler listings and side files are read by Z Abend Investigator module HFZDA.
  - Using the HFZXSFOR compiler listing/side file search and override exit
    If the HFZXSFOR exit is available, Z Abend Investigator invokes it to allow programmatic specification of the location of compiler listing or side file data.
  - Compiler listings and side file attributes
  - Using the HFZRLOAD DDname for CSECT mapping
  - HFZDATST side file availability test utility
  - ISPF-packed compiler listings
  - Providing Java source information to Z Abend Investigator
    There are two options for providing Java™ application source information to Z Abend Investigator.
  - HFZSBLKO
    The HFZSBLKO utility converts compiler listings generated with the BLKOFF option into a format simulating the required NOBLKOFF option.
- Customizing the CICS environment
- Customizing the DB2 environment
- Customizing the IMS environment
- Customizing the Java environment
- Customizing the Z Abend Investigator Japanese feature
- Verifying Z Abend Investigator customization
- Managing history files (HFZUTIL utility)
  The HFZUTIL batch utility can be used to perform history file management functions, such as listing and deleting history file fault entries.
- Providing application-specific explanations and descriptions
- Maintaining Z Abend Investigator
- Disabling Z Abend Investigator
- Customizing Z Abend Investigator by using user exits
- Z Abend Investigator on VS Code
  HCL Z Abend Investigator is a host component and supports a client that supports various interfaces such as Microsoft Visual Studio Code IDEs.

HFZSBLKO

The HFZSBLKO utility converts compiler listings generated with the BLKOFF option into a format simulating the required NOBLKOFF option.

The NOBLKOFF option is required for Enterprise PL/I as described in Required compiler options for HFZLANGX. If your compiler listings were created using BLKOFF, you can use the sample REXX utility HFZSBLKO provided to attempt to convert the listing to appear as if it were created with NOBLKOFF. This sample is provided as a member HFZSBLKO in the HFZ.SHFZSAM1 data set.

This sample EXEC can be invoked either as a Z Abend Investigator compiler listing user exit or it can be used against a listing file data set or a specific member within that data set. Complete usage instructions are provided in the HFZSBLKO sample.

Note:

While this sample has been tested using different PL/I compiler versions and programs, it is not guaranteed to work in all scenarios. You must review the modified output to ensure accuracy.
