Did you go through the external tutorial? If not, you should do that
first. You'll learn that you can't just execute a 'C' file, you have
to compile and link it first. Cloning and modifying this tutorial
stack is the best approach to writing a new external, since you can
make changes one at a time. If you just try writing an external from
scratch, it most likely won't work, and debugging externals is
extremely difficult (although not as difficult as debugging externals
in HyperCard, where a wayward external can easily lock up the whole
system ;-)
Externals are started up automatically when a stack is opened. There
is a stack property "externals" that is a list of these executables.
You can set it with the "Components" dialog box from the "Stack
Properties" dialog, or directly using the Message Box.
