The system API has a slight advantage in having only one parameter, and
in making it possible to do the call and test the return code on the
same line, but I think the disadvantage outweighs the advantages.

The disadvantage of system() is that when the command fails, system()
removes the final exception message from the joblog.  You can get the
7-byte exception ID, if you code for it in your program, but you lose
the replacement text which may be critical to figuring out what went
wrong if your program fails unexpectedly.
