Steve,

Thanks for pointing me to PEP 302 and the imp module.
It looks like "imp.load_compiled(name, pathname[, file])" is what I
need, but the description of this method (and similar methods) has the
following disclaimer:
Quote: "The file argument is the byte-compiled code file, open for
reading in binary mode, from the beginning. It must currently be a real
file object, not a user-defined class emulating a file." [1]
I tried using a cStringIO object vs. a real file object, but the help
documentation is correct - only a real file object can be used.
Any ideas on why these modules would impose such a restriction or is
this just an historical artifact?
Are there any techniques I can use to avoid this physical file
requirement?
Thanks,
Malcolm
