SDF interface to high-level programming languages

SDF offers an interface for programs written in High Level Languages. Programs written in any of the programming languages COBOL, FORTRAN or C can use the functions of SDF macros directly, i.e. no Assembler subprograms are required in order to provide the program with an SDF user interface. SDF supplies the appropriate function calls in support of the functions of the SDF macros RDSTMT, CORSTMT, TRSTMT, CMDRC, CMDSTA and CMD. In addition, SDF offers functions that facilitate the analysis of the standardized transfer area.

For a detailed description of the SDF interface to high-level programming languages please refer to the “SDF-A” manual [4].

The interface to higher programming languages only supports the old format of the standardized transfer area. The new format can only be used through the Assembler interface!
