Henry,
Okay, I'm stumped. What you suggests works nicely, but I can't figure
out how to put it in a pro-verb. That is,
]a=: i. 3 4 5
0 1 2 3 4
5 6 7 8 9
10 11 12 13 14
15 16 17 18 19
20 21 22 23 24
25 26 27 28 29
30 31 32 33 34
35 36 37 38 39
40 41 42 43 44
45 46 47 48 49
50 51 52 53 54
55 56 57 58 59
2 3 3 {"0 1 a
2 7 12 17
23 28 33 38
43 48 53 58
selcol=: 2 3 3 & {"0 1
selcol a
2 3 3
7 8 8
12 13 13
17 18 18
22 23 23
27 28 28
32 33 33
37 38 38
42 43 43
47 48 48
52 53 53
57 58 58
Executed as a command, it does exactly what I want. When I try to make
it into a pro-verb, it does something different, and I don't yet see a
way back. I know it will be obvious when someone explains it.
