Think of it this way...  If you wanted to show the command, rather than 
execute it, what would you do?  Then, replace "SHOW" with "SYSTEM".

If you want to pass the value of the field FC, rather than the literal "FC", 
then you need to tell filePro to do so, by not putting FC in the string literal:

     system "tail +" { fc & " /u/appl/fpmerge/filename >/other/filename"
