Create unique temporary file [message #40677]

I need some robust way to create a temporary file. The filepath
function will get you part of the way toward this goal since it can
prepend your system's temporary directory to the file name. But you
still have to come up with a good filename.

filename = FilePath('myfile.txt', /TMP)

The above command will do the job if you only have one copy of the
program running. If there are two or more copies of the program
running, or even a single program running in multiple threads, there's a
possibility of collision when two processes or two threads attempt to
use the same temporary filename at the same time.

What I'd like is some way to generate a completely unique filename
except for the extension to reduce the probability of a collision. Any
bright ideas?
