dear Guillermo J. Rozas and Mark (markf)  at altdorf.ai.mit.edu !!

thank you very much for the information about invoking system-calls in 
MIT_SCHEME - programs; i have just tested your recommended code and it works 
really fine ! 
my problem was to establish a rendezvous-like mechanism between two processes
(one PROLOG program and a SCHEME program) for information handling, and all
i could do yet was a "busy-wait" for the process that should better block 
istelf on a semaphore; with the system-call procedure i should be able to
do this more proper and fast (for example with the UNIX signal-mechanism i
hope).
sorry that i wrote in german language since the years in school are far away,
but i really thought you were located in Swizzerland (of course, every student
of computer-science in germany has heard about your famous MIT and so I!).
i hope the syntax and orthography of this text are not TOO wrong, 

                              sincerly yours, Thorsten Hasbargen !!!
