[Jprogramming] the equilent of a scan with cut?

[Steven Taylor]

Hi,

How do I do this with a cut?

   A=.(i.30) ,: (100 + i.30)
   2 <\ |: A



Dan gave this example:

  3 3 <;._3 i. 4 4

        +--------+--------+
        |0 1  2  |1  2  3 |
        |4 5  6  |5  6  7 |
        |8 9 10  |9 10 11 |
        +--------+--------+
        | 4  5  6| 5  6  7|
        | 8  9 10| 9 10 11|
        |12 13 14|13 14 15|
        +--------+--------+


I'm having trouble understanding the J dictionary on this reading


Thanks,

--Steven
