Mainframe Analyzer - 1.4

Extension ID


What’s new?

See Mainframe Analyzer - 1.4 - Release Notes .


This extension provides support for Mainframe (Cobol, CICS, JCL, IMS…). If your application contains Mainframe source code and you want to view these object types and their links with other objects, then you should install this extension.

Technical information


When installed, this extension replaces the Mainframe Analyzer embedded in CAST Imaging Core:

  • The Mainframe Analyzer embedded in CAST Imaging Core will continue to exist and will be shipped “out of the box” with CAST Imaging Core.
  • Critical bugs will continue to be fixed in the Mainframe Analyzer embedded in CAST Imaging Core but no new features or functionality will be added.
  • The Mainframe Analyzer extension will have exactly the same features and functionality on release as the Mainframe Analyzer embedded in CAST Imaging Core, therefore analysis results will be identical.
  • The Mainframe Analyzer is compatible with CAST Imaging Core ≥ 8.3.26.
  • All future development of the Mainframe Analyzer (new features, functionality etc.) will be completed in the Mainframe Analyzer extension only. Critical bug fixes will be fixed in the Mainframe Analyzer extension (as well as the analyzer embedded in CAST Imaging Core).
  • The behaviour is as follows:
    • Nothing is automatic - the Mainframe Analyzer extension must be manually downloaded and installed in order to use it (* see note below)
    • If the extension is installed, it will automatically be detected and will be used rather than the analyzer embedded in CAST Imaging Core.
    • Once the extension has been installed and used to produce analysis results, it is not possible to reverse this choice by removing the extension and re-analyzing the source code again.

Starting CAST Console 1.26, if Mainframe source code is detected during delivery, the Mainframe extension will automatically be downloaded and installed replacing the Mainframe Analyzer embedded in CAST Imaging Core.

Features / support added in the extension

IBM MQ Series

The analyzer supports IBM MQSeries (see Technical Notes ), but the following support has been added in the extension:

  • MQSeries objects are now supported via Batch and CICS environments (ex: CSQBOPEN, CSQCOPEN).
  • MQSeries objects are now identified without the copybook CMQODV.

Function Point, Quality and Sizing support

This extension provides the following support:

Function Points
(tick) A green tick indicates that OMG Function Point counting and Transaction Risk Index are supported.
Quality and Sizing (tick) A green tick indicates that CAST can measure size and that a minimum set of Quality Rules exist.


This extension is compatible with:

CAST Imaging core release Supported
≥ 8.3.26 ✔️

Dependencies with other extensions


Parametrization_Cobol.xml file

The extension is shipped with a parameterization XML file called Parametrization_Cobol.xml file - see Analysis configuration  for more information about this. This file takes priority over the same file delivered in CAST Imaging Core (in Configuration\Parametrization\Cobol) therefore if you are moving to using the Mainframe Analyzer, you must ensure the following:

  • You must copy the file (or the rules in file) from the CAST Imaging Core installation folder Configuration\Parametrization\Cobol into the deployed extension on your Node(s): %PROGRAMDATA%\CAST\CAST\Extensions\com.castsoftware.mainframe.-funcrel\configuration\parametrization\Cobol

  • If you upgrade to a newer release of the extension, and if you have modified the Parametrization_Cobol.xml file to add custom rules, you must ensure that you copy the file (or the rules) into the new extension installation location, e.g.:

    • Current extension installation location: %PROGRAMDATA%\CAST\CAST\Extensions\com.castsoftware.mainframe.<version1>-funcrel\configuration\parametrization\Cobol
    • New extension installation location: %PROGRAMDATA%\CAST\CAST\Extensions\com.castsoftware.mainframe.<version2>-funcrel\configuration\parametrization\Cobol
