[HECnet] Slightly OT - How to concatenate multi line strings in DEC COBOL

There is a manual in the "gray wall" just about that. I can't search for it now, but iirc the title is easy to pick up. Basic summary: scalars are passed by reference, strings are passed by descriptor address. VMS C provides macros to build and manage descriptors (the ASCIZ convention is fortunately not used). The HP OpenVMS Calling Standard manual I think is what you are referring to. Unfortunately I don't think it's going to help Sampsa much - I had a quick flick through and it's all low level detail, it doesn't contain any examples of calling one language from another. More of a specification of the interface for new language implementations. Mark -- http://www.wickensonline.co.uk http://declegacy.org.uk
