Thanks for the reponse, I found the above mentioned reference manual
after a fashion and sure enough went ahead and generated a couple of
pages of hand coded Beta files. I do have some outstanding questions
which I have already posted. Notably the calling sequence for C variables
passed by reference, but not declared externally. Is <ptr> an attribute
of the CStruct pattern? (I would like that approach ).
