Not all Bourne shells are bourne equal.  (Sorry)  *If* your Bourne
shell has shell functions, yes; if not, you are also correct.

How can you tell whether your Bourne shell has shell functions?
Try Larry's example chdir().  If sh says

	syntax error: `(' unexpected

it does not have shell functions.
