[q-lang-users] "and then" and stack usage

[ww <wwa...@ea...>]

Hi,

I've been exploring Q recently and I've noticed that "and then" doesn't
seem to run in constant space. From it's definition (in the docs), I was
expecting that it could reuse the stack frame but that doesn't seem to be 
the case. Am I missing something?

I'm running QPad version 5.0.

Thanks,

Walt
 
My Example;

randoml N:Int  = randoml [] N;

randoml L:List N:Int = randoml (push L random) (N-1) if N>0;
                               = L otherwise;

% C:\Documents and Settings\ww\My Documents\randoml.q

==> def A=randoml 10

==> def B=randoml 100

==> (A=A)
true

==> stats
0 secs, 31 reductions, 41 cells

==> (B=B)
true

==> stats
0 secs, 301 reductions, 401 cells

==> version
"5.0"
