Most of the examples and discussions are about C, but there are some brief assembler bits. And there is a discussion of assembler considerations (not just for DLLs) in Chapter 29, including the various macros you need. To be clear, HLASM *is* explictly a supported language for both writing and invoking DLLs under LE. See "Support for DLLs" at the very start of Chapter 4. I haven't played with this for many years, and am not current, but other people on this list have written about it - maybe John McKown? And there was the Trainer's Friend guy (Steve Comstock?), who gave courses on this and related LE matters. He made his course materials available for sale when he closed the business. Maybe they are still out there? Ah - I see some of it is now on Amazon. Not free, but maybe a good deal. http://www.trainersfriend.com/zOS.shtml I have no connection, etc... Tony H.
