How CULLUS22 Works

CULLUS22:

1. Uses a specified field from the input file as a retrieval key
2. Allows the retrieved ISAM records to be moved to an input field or a work field, as specified in the CA Culprit parameters
3. Uses a communication switch to:
   • Receive instructions to open or close the ISAM file
   • Return processing status information
4. Requires separately compiled and linked versions of CULLUS22 for each ISAM file accessed during a single CA Culprit run
