/BLOCK_LIMIT=([lowlim,]uplim)
       /NOBLOCK_LIMIT

    Limits the size of print jobs that can be processed on an output
    execution queue. This qualifier allows you to reserve certain
    printers for certain size jobs. You must specify at least one of
    the parameters.

    The lowlim parameter is a decimal number referring to the minimum
    number of blocks that are accepted by the queue for a print job.
    If a print job is submitted that contains fewer blocks than the
    lowlim value, the job remains pending until the block limit for
    the queue is changed. After the block limit for the queue is
    decreased sufficiently, the job is processed.

    The uplim parameter is a decimal number referring to the maximum
    number of blocks that are accepted by the queue for a print job.
    If a print job is submitted that exceeds this value, the job
    remains pending until the block limit for the queue is changed.
    After the block limit for the queue is increased sufficiently,
    the job is processed.

    If you specify only an upper limit for jobs, you can omit the
    parentheses. For example, /BLOCK_LIMIT=1000 means that only jobs
    with 1000 blocks or less are processed in the queue. To specify
    only a lower job limit, you must use a null string ("")  to
    indicate the upper specifier. For example, /BLOCK_LIMIT=(500,"")
    means any job with 500 or more blocks is processed in the queue.
    You can specify both a lower and upper limit. For example,
    /BLOCK_LIMIT=(200,2000) means that jobs with less than 200 blocks
    or more than 2000 blocks are not processed in the queue.

    The /NOBLOCK_LIMIT qualifier cancels the previous setting
    established by the /BLOCK_LIMIT qualifier for the queue.
