It often is a compile-time error, as opposed to run-time.  However, if
Joe meant to distinguish between 'Give the ball to Jamie' and 'Give
the ball', it is a syntax error: 'Give( the ball, Jamie )' vs. 'Give
( the ball )'.  (Wait, is 'give the ball' a syntax error or what?)

In fact, NLs clearly mark the difference between commanding a process,
and nominating it.  'Go to the store' is the imperative, while 'Going
to the store' is the nominative.  In this case, 'ing' serves to mark
the absence of parentheses, and the bare form, without 'ing', marks
the call.
