PROLOG

       This manual page is part of the POSIX Programmer's Manual.  The
       Linux implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior),
       or the interface may not be implemented on Linux.

NAME

       continue — continue for, while, or until loop

SYNOPSIS

       continue [n]

DESCRIPTION

       If n is specified, the continue utility shall return to the top
       of the nth enclosing for, while, or until loop. If n is not
       specified, continue shall behave as if n was specified as 1.
       Returning to the top of the loop involves repeating the condition
       list of a while or until loop or performing the next assignment
       of a for loop, and re-executing the loop if appropriate.

       The value of n is a positive decimal integer. If 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 break utility.
