I have kermit'd back the modified sources for this program.

The original did not work at all.......
First I had to add logic to swap bytes as the system I have
has all the data swapped from the VAX. (Valid S320 running a modified BSD
4.2).

Next the program would bomb after retreiving a part of the data. This
was due to the fact the software had no idea of XOR blocks in the
backup save_sets. The default is every 10 blocks. and it is an XOR of
the previous 10 blocks so any trashed block can be recreated by XORing 
the other 9 blocks with this block. it works really nice. for those
that do not care the software would have worked on backups
with a /group=0 on the command line, but that does not solve the problem
for novice users who do not understand such things.
I added the logic to handle (and ignore) the XOR blocks as in the short
of it I think it is actually for the best. Anybody that wants to add
the code to make the XOR work, have fun, it does not appear to difficult
but I really do not think it necessary.

There are two makefiles now. one that will use the SWAB for swap bytes
(the default) and the other that does not swap bytes.

use as you wish.
If I fix any other stuff I find I will dump it back to you for
re-distribution...

barry.

you can find the stuff in DRC0:[suskind.read_vms]
