Writing a User Exit Module

CA IDMS Extractor Release gives you the ability to write an assembler user exit module to be called prior to a record's being written to the Extract File. This exit is called by the Database Extract Component when:

• CA IDMS Extractor is walking the source database looking for records to be extracted, and
• A record meets its Record Level Selection Criteria.

You can change the record data, add or delete fields to/from the record data, or prevent the record from being written to the file. We supply the descriptions of the parameters that are passed to your exit module in both Assembler and COBOL formats.
