Ross,

You could try my frame tools, available at

http://cimss.ssec.wisc.edu/~gumley/frame.html

For example,

PRO TEST_FRAMES
fset, frames=10
for i=1,10 do begin
  xyouts, 0.0, 0.0, strcompress(i), charsize=10.0, /normal
  af
endfor
lf, del=1.0/25.0
END

As long as you are logged in at the console of the machine running IDL,
it should run fast enough. Let me know if it works for you.

Cheers,
Liam.
