- .SH SYNOPSIS
- .LP
- .nf
- continue \fB[\fIn\fB]\fR
- .fi
- .SH DESCRIPTION
- If
- .IR n
- is specified, the
- .IR continue
- utility shall return to the top of the
- .IR n th
- enclosing
- .BR for ,
- .BR while ,
- or
- .BR until
- loop. If
- .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.
- .P
- The meaning of ``enclosing'' shall be as specified in the description of the
- .IR break
- utility.
