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.
