Although this extension is officially supported by CAST, please note that it has been developed within the technical constraints of the CAST Universal Analyzer technology and to some extent adapted to meet specific customer needs. Therefore the extension may not address all of the coding techniques and patterns that exist for the target technology and may not produce the same level of analysis and precision regarding e.g. quality measurement and/or function point counts that are typically produced by other CAST AIP analyzers.

Grade values following upgrading from CAST AIP 7.0.x

If you are installing the extension while upgrading from a CAST AIP 7.0.x please note that when consulting the results of your snapshot immediately after the migration, you will see that the grade values of multiple Quality Rules have been modified even though the number of failed and total checks is exactly the same as before the migration.

The difference in grade values is due to the different grade threshold values that are used in the the two releases of CAST AIP: the new grade threshold values are applied by during the Assessment Model import. Since no specific grade threshold values are specified for any RPG Quality Rules, CAST applies the default grade threshold values during the Assessment Model import. Please note that the default grade threshold values have been also updated in CAST AIP 7.2.x and above.

Take the following example for the Quality Rule: Avoid Subroutines with a very low comment/code ratio (RPG400)

CAST AIP 7.0.x

  • 2 failed checks
  • 78 total checks
  • 97.44, grade = 2.61

CAST AIP 7.2.x and above

  • 2 failed checks
  • 78 total checks
  • 97.44, grade = 3.83
