Embodiments include methods, and computer system, and computer program products for generating ease of use interfaces for legacy system management facilities (SMF). Aspects include: retrieving an SMF record from an SMF data source through an SMF data interface from a file, over a network or via a real-time API, SMF record having a data control section (DSECT) with code comments for storing a mapping of SMF record defining data structure of SMF record with one or more fields, converting mapping of SMF record into an intermediate format representing mapping of SMF record and corresponding information extracted from the code comments among the one or more fields of SMF record, generating at least one application programming interface (API) in a different computer language using intermediate format, and accessing SMF record using API generated. Different computer language may include Java and intermediate format may include Extensible Markup Language (XML).
