    If you are running the Windows version of the environment there is
a performance advantage to using the Misc window.  ACL does not compile
functions when they are loaded (MCL compiles everything by default).  To
improve performance, the environment compiles the Misc window when you
open a model and whenever you press the reload button on the Control 
Panel.  Files included with the model are not compiled.  You could compile
the files manually, and then load the fasl with a load call in the model, 
but you would not be able to edit the file using the model manager, 
because it would try to open the fasl for editing.  You could also use the
compile function to load the file, but then it would not be included 
in the model manager list of files.
