Producing subroutine interface applications

On the basis of rules and examples, this section explains the production of programs in BS2000 which use EDT as a subroutine or which are to be called by EDT as user routines by means of the @USE or @RUN statements.

The languages C and Assembler are considered. For other languages, EDT provides only ILCS-compliant linkage. In such cases, it is the responsibility of users themselves to ensure the dynamic loading, linking and initialization of the required runtime routines.
