Hi Gregg,
Thanks for your reply.
I know how to use the system() call; however, I really do not want the overhead of
the shell for every operation I need to do. I can live with the interpreted nature
of Icon. I'm still awaiting news on Unicon. My thought was to use loadable
functions (or external calls) to support many of the features I need, since I
have done this before to include DBM support in Icon.
Best,
George
