    There are many ways to deal with this, but here's one of the simplest.
    If you want to select rows 50 thru 70 of an input set, use a Filter node with this bit of brainscript:

    emit *
where execCount >= 50 and execCount <= 70
    If the dataset has a large number of records, this will speed it up a good bit:
    emit *
where execCount >= 50 and execCount <= 70
if execCount>70 then consume(1,true)   #stop reading more input records
