When the next statement is executed, the result is to exit from the current statement sequence (that is, the do-end do block) that corresponds to the innermost repetition (for/while/do) statement within which it occurs.

To exit from the current statement sequence means to allow execution to proceed with the next iteration of this repetition statement.

Note: To "proceed with the next iteration'' implies to increment the index of iteration, and then to apply the tests for termination (specified by the to-clause and the while-clause, if present) before proceeding.  Thus, an exit from the loop may occur.

It is an error if the next statement is executed in a context other than within a repetition statement.

In Maple V Release 5.1 and earlier, next was just a Maple symbol. In Maple 6 and later, next is a keyword in the Maple language.
