Lisp proxy stubs talk via a simple IPC layer to Cobol agents which in turn access the database for you. All you need is the Cobol record declaration (the copy file, in Cobol speak) and cobstor will automatically generate the Cobol agent and the Lisp proxy for you.
It's been developed on CMUCL+AcuCobol but it should be easily portable to other Lisp systems that support MOP, and Cobol systems with socket primitives.
