The runtime option "CSI" has been added to CA JCLCheck to replace the existing "VSAM" option. The "CSI" option uses a new program to read ICF catalogs providing enhanced functionality as well as improved performance for CA JCLCheck.
The VSAM option is no longer maintained and should be considered obsolete.
At z/OS 2.2, an erroneous error message, CAY6089E DATASET dsname is NOT a PDS will occur if the VSAM option is used. To prevent this error message, remove the VSAM option and the CSI option will be used as the default.
