I suspect it may be easier just to call the C program using the  
'system' call, but frankly, reading this thread brings out the pedant  
in me:

You can state your question(s) more precisely.  Do it. A more precise  
question will yield a more precise answer.

It sounds like your first questions have to do not with Scheme, but  
rather with building a mental model of OS-level processes (especially  
shells) and how they interact.

Apologies for the supercilious tone,

John Clements
