[daip] FILLM message

[George Moellenbrock]

Eric, Claire-

Thanks for having a look at that archive file.  My guess is that putting it
on my
memory stick (a Windows filesystem) must have garbled it.  CASA also choked
on it at the same point.  Does this sound plausible, Eric?

I'll avoid using the memory stick for data in future.

Thanks,
George
