Record Access and Processing › Addressed Access

Addressed Access

CA IDMS VSAM Transparency supports addressed access for key-sequenced data sets and entry-sequenced data sets. When addressed access is used, CA IDMS VSAM Transparency uses the CA IDMS/DB db-key in place of the RBA.

Addressed access can be used with:

• Direct processing
• Sequential processing
• Backward processing

Direct, sequential, and backward processing are discussed below.
