I need to write a script to find all rows in the table with value > 50 and return 10 rows right after those rows. Could someone help me with this script please? Thank you!
Without any knowledge of the data you have here is one option you could start with (it looks for values over 120 not 50)
Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Big Class.jmp");
r = As List(dt << Get Rows Where(:weight > 120));
rs = {};
max_rows = N Rows(dt);
For Each({cur_r}, r,
Insert Into(rs, Index(cur_r + 1, Min(max_rows, cur_r + 10)));
);
show(r);
show(rs);
// r = {2, 4, 7, 18, 30, 37, 39, 40};
// rs = {[2 3 4 5 6 7 8 9 10 11], [4 5 6 7 8 9 10 11 12 13], [7 8 9 10 11 12 13 14 15 16], [18 19 20 21 22 23 24 25 26 27], [30 31 32 33 34 35 36 37 38 39], [37 38 39 40], [39 40], [40]};
