I think I have figured out what this task specification is asking for. So I wrote some J code that I expect might work here.
NB. http://rosettacode.org/wiki/Man_or_boy_test A=:4 :0 ctx=.cocreate'' B__ctx=:B k__ctx=:x '`x1__ctx x2__ctx x3__ctx x4__ctx x5__ctx'=:y if.k__ctx<:0 do.a__ctx=:(x4__ctx + x5__ctx)'' else. ctx B '' end. a__ctx ) B=:4 :0 ctx=.x k__ctx=:k__ctx-1 a__ctx=:k__ctx A ctx&B`x1__ctx`x2__ctx`x3__ctx`x4__ctx ) 10 A 1:`_1:`_1:`1:`0: My problem is that this dies with a stack error. With debug turned on, #13!:13'' gives me 5001 stack frames. So, searching jsoftware.com for pages dealing with this issue (I know that the stack limit can be lifted), I find: http://www.jsoftware.com/help/release/recurlim.htm So... first, I had to locate a copy of dumpbin and editbin. And I am not sure what I should have been doing if I were running on linux or a mac. Eventually, I located a copy -- it is not a standard part of windows -- and then with some more work I addressed a problem where it could not find a .dll it needed. So, then, I tried editbin /stack:6000000 on my j.exe, but when I ran this code again, it still blew up with 5001 for #13!:13''. So I tried changing the .dll again, this time changing the limit to 9000000 but the coded died egain with the same size of stack. So... how should I address this kind of problem?
