I tackled the porting of some MIT music synthesis code from VAX over to MSC on a PC/AT a few years ago. The biggest problem was (deja vu?) VAX-hackers allocating enormous arrays as automatics. (A pair of 10,000 element float arrays, for example...) Anyway, Craig Harris wanted it done, so I did it. MSC requires HUGE pointers and use of halloc() (if memory serves, it has been a while) to reference objects that big. But the code can be re-written with a bit of care and it can be made to work. The second biggest hassle was the penchant of VAXhackers for de-referencing NULL. Aside from whupping them upside the head with an ASR-33, I have no solution for that. -- Russ Cage Ford Powertrain Engineering Development Department Work: itivax.iti.org!cfctech!fmeed1!cage (CHATTY MAIL NOT ANSWERED HERE) Home: russ@m-net.ann-arbor.mi.us (All non-business mail) Member: HASA, "S" division.
