I just recalled, if you have "toolshed" on the pc, I believe that there 
is an "os9 format filename" utility in there.  See the toolshed docs 
because you will need to add it to your $PATH environment before it will 
work.

Here on this linux box, $PATH is:

/opt/toolshed/build/unix/os9:

Followed by most of the other stuffs I need. It is a : separated list on 
linux. Probably different on winderz, but the general idea is the same.
