(I added the quote symbols myself, by hand.  Let's see if that  works.)
 
I think I answered the wrong question -- the query was how to make a  
shell(command string) function return a value.  Well, it should return the  shell's 
value -- in UNIX a 0 for success, else some integer error code.  I  think OS9's 
conventions are different, maybe not.
 
Anyway, I agree, I see no way to get multiple values back.  Go the  
assembler-fuctnion route.
It's not hard to write your own shell() function to execute a given command  
string and return the success/fail value.
Hope I answered the right question this time --Mike  K,
