Just as the \code{for} and \code{do} constructs were combined
with the \code{parallel} construct for convenience, so too, the combined
\code{parallel}~\code{masked}~\code{taskloop} and 
\code{parallel}~\code{masked}~\code{taskloop}~\code{simd}
constructs have been created for convenience when using the
\code{taskloop} construct.
  
In the following example the first \code{taskloop} construct is enclosed
by the usual \code{parallel} and \code{masked} constructs to form
a team of threads, and a single task generator (primary thread) for
the \code{taskloop} construct.

The same OpenMP operations for the first taskloop are accomplished by the second
taskloop with the \code{parallel}~\code{masked}~\code{taskloop} 
combined construct. 
The third taskloop uses the combined \code{parallel}~\code{masked}~\code{taskloop}~\code{simd} 
construct to accomplish the same behavior as closely nested \code{parallel masked},
and \code{taskloop simd} constructs.

As with any combined construct the clauses of the components may be used
with appropriate restrictions. The combination of the \code{parallel}~\code{masked} construct
with the \code{taskloop} or \code{taskloop}~\code{simd} construct produces no additional 
restrictions.
