VMS Help START, /QUEUE, Qualifiers, /ALIGN  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /ALIGN[=(option[,...])]

    Prints alignment pages to aid in aligning printer forms. Use this
    qualifier only when restarting an output execution queue from a
    paused state.

    After the alignment is complete, the queue enters a paused state
    until you restart it by reentering the START/QUEUE command.
    Printing resumes from the point where alignment data started;
    that is, the task is backspaced over the pages printed for
    alignment.

    Possible options are as follows:

    MASK    Specifies that input data is masked by replacing
            alphabetic characters with x's and numbers with 9s;
            nonalphanumeric characters are not masked. Mask
            characters allow you to prevent the printing of sensitive
            information. If you omit the MASK option, data is printed
            unaltered.

    n       Specifies the number of alignment pages to print. The
            value of n can be from 1 to 20. By default, one page of
            alignment data is printed.
