You WILL have to copy the file to the other machine. How else would
the vm find it? I suppose you could read the file in, encode it
somehow into a variable then use that encoding as a hard coded
variable in the sav file (hard to describe) - but that seems like a
lot of hard work. Why can't you just make the file available to the
vm?
Maybe the better question is - what do you need the "dummy" file for?
Can this be changed to, say, a template or an anonymous structure,
etc. Something that can be coded into idl and not have to be read
from the file system...
Just a thought.
