This example uses the CVAFFILT macro to read all format-1 and format-3 DSCBs for specific data sets within a given VTOC as well as for all data sets within a given VTOC. It will also calculate the number of DSCBs and print the totals and appropriate messages to an output file. Refer to the documentation within the sample source in CVAFFILT Macro Overview and Specification for setup requirements, program logic, and expected output.

The CVAF parameter list, buffer list, and filter criteria list are defined in the sample source. The ICVAFPL macro generates the CVAF parameter list, the ICVAFBFL macro generates the buffer list, and the ICVFCL macro generates the filter criteria list.
