.IR n
is not specified,
.IR continue
shall behave as if
.IR n
was specified as 1. Returning to the top of the loop involves
repeating the condition list of a
.BR while
or
.BR until
loop or performing the next assignment of a
.BR for
loop, and re-executing the loop if appropriate.
.P
The value of
.IR n
is a positive decimal integer. If
.IR n
is greater than the number of enclosing loops, the outermost enclosing loop
shall be used. If there is no enclosing loop, the behavior is unspecified.

The meaning of ``enclosing'' shall be as specified in the description of the
.IR break
