The .NO NUMBER command suspends normal page numbering. The
    .NUMBER PAGE command resumes normal page numbering, having kept
    track of the numbering while .NO NUMBER was in effect; or it
    allows you to specify the beginning of a new number sequence by
    specifying a number for the next page. (See also .NUMBER RUNNING,
    .DISPLAY NUMBER, .NO PAGING, and .HEADERS ON.)
