Thanks. I've had a look and I reckon the easiest way of doing this is
to write a field line plotter (sorry,
code-that-takes-a-vector-field-and-traces-lines-which-are-ta ngent-to-the-vector-field-from-a-number-of-seed-points)
in C. I can't see much point in having to hack a huge expensive
package like IDL to do something simple slowly.
Thanks again though!
