DESCRIPTION

The continue utility shall return to the top of the smallest enclosing for, while, or until loop, or to the top of the nth enclosing loop, if n is specified. This 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 decimal integer greater than or equal to 1. The default shall be equivalent to n=1. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used.
