Kevin;
The point I was making was that there are things that MUMPS does really
well and there are things that it does not perform well at. In such cases,
one needs to use other tools. The endian issue is one of underlying
operating system and hardware architecture. This is an area that MUMPS
specifically avoided in order to maintain platform independance. There are
big assumptions that need to be made that bar transport of such an interface
to another platform. For those issues, VistA usually calls out to the
underlying vendor tools or out to user supplied tools.
Sometimes it is better to let the underlying OS do some of the work.
That was what I was aluding to.

Are you making this more difficult that it has to be? (I can't
*imagine* you doing that! :-) )
I don't know about the big/little endian issues. I am not planning to
store two-byte words, so I don't think this comes into play. I will
just store the bytes as they come in the stream.
And I don't want to use a GT.M unique solution, as that will greatly
limit potential use by others.

P.S. I read that using this syntax:
use IO:(NOTERMINATOR) is supposed to make the stream not stop at
"terminator" characters.
But it doesn't seem to work for me yet.
