DIL User Reference Manual

The DIL User Reference Manual provides a comprehensive guide to the Data Interchange Library (DIL). DIL is a set of callable subroutines designed for COBOL and FORTRAN programmers to facilitate data exchange, task-to-task communication, and remote file access within a heterogeneous computing network consisting of TOPS-10, TOPS-20, and VMS operating systems.

Key contents include: * Data Conversion Routines: Facilitates translating fields between different system data types (alphanumeric strings, fixed-point binary, packed decimal, display numeric, and floating-point binary). * Task-to-Task Routines: Enables data transfer between programs on different systems via logical links, including routines to open/close links, accept/reject connections, and send/receive data or interrupt messages. * Remote File Access (RFA) Routines: Allows access to sequential ASCII files on remote systems, supporting reading, writing, appending, and deleting operations. * System-Specific Implementation: Detailed sections for implementing DIL on TOPS-10/TOPS-20 versus VMS, including compilation, linking, and status code handling. * Appendices: Provides language-specific data values, detailed data format diagrams, and extensive error message documentation.
