Use something like this:
  exec mycommand -flags -blah foobar.txt

This is covered on page 111 or "Tcl and the Tk Toolkit" by Ousterhout,
ISBN: 0-201-63337-X, which is a book that I use a lot when doing Tcl things.

No problem.
Get a copy of the Tcl book above, or another Tcl reference, it will save
you a lot of time and energy. Anyone doing non-trivial work with VMD
should definitely plan on having a Tcl reference handy.
