    ...I would like to know if there is a way to interface Icon with C
    (i.e. call C functions from Icon, or call an Icon procedure from C) ??


It is fairly easy to call C functions from Icon under Unix if you're
willing to write the functions specifically to interface to Icon.
See the "dynamic loading" section of
    http://www.cs.arizona.edu/icon/docs/ipd240.htm

(If anyone has figured out how to make this work under IBM AIX 4.2,
 I'd like to hear from them; it doesn't like my shared library. )

There's no easy way to call Icon code from C other than by communication
with an Icon program running in a separate process.  (System(), pipe, etc.)
