Yes, and it was compiled and built in a number of places (since multiple copies 
were checked out from CVS) at your very institution. We didn't use mv167, but we 
did use a number of 68k architectures, so mv167 will not be any different. We 
used it for the UFTI project. One place it can be found is 
/sw4/npr/ukroot/ufti/src/fitsio. Talk to Alan Bridger about it (if you haven't 
already).

The two suggestions I have are:

1. You need a large stack, since deep down it pops about 30k onto the stack -
   this single function needs more stack than the default VxWorks stack size.
   We run it with 100k stacks, but 50 k would probably be OK.
2. Make sure that you have NFS working on the directories you are writing to 
   and reading from.

There were a number of other little things, so use our source code, not yours.
