I have Cc:d this reply to Terry Robb who now works for Wolfram Research.

InterCall worked very well under Mathematica Version 2.2, but this
release is no longer supported. It was intended that Wolfram Research
would distribute InterCall once it was compatible with Mathematica 3.0
(and future versions) but, due to changes in MathLink between 2.2 and
3.0, certain functionality of InterCall is still not available.  

I have strongly encouraged Terry to update InterCall so as to fix or
workaround these problems but he has been too busy with other projects
(which is, in my opinion, a great pity).

For your information, the InterCall package is fully documented in "The
InterCall Book", edited by Michael G. Trefry and Paul C. Abbott, 1998,
ISBN:0-646-35666-6, and available at
