Re RTLD_LAZY, much appreciated.
Re ⎕NC, that's the advantage of some nut writing obscure code: it
identifies obscure bugs.

Hi Henrik,
thanks for the reminder. Fixed in *SVN 1783*.
I also spotted an error which caused ⎕NC to return a wrong value for ⍺,
⍵, etc.
⍺ and ⍵ came after ⎕NC was first implemented, and I failed to handle
them properly.
Note also that ⎕NC is slightly different from IBM's by having different
Hey, Jürgen,
Thanks.
This is part of continuing work on the mtx native function thing I put
up six months ago, and just for the sake of consistency, I was trying
make all the mtx functions lambdas, but it's no problem to use a ∇
function when I need ambivalence. (If I'd looked at how you imp

The reason is this:

optionally one for ELSESTAT.

Hi Hendrik,
as far as I remember: in GNU APL a lambda is pretty much a regular
defined function.
A nomadic lambda is simply a dyadic lambda which test for the presence
for its left
argument (read: ⎕NC lambda = 2).Tour tryit needs to check that before ⍺
is referenced).
Best Regards,
Jürgen
Yes viz.:
tryit←{⍺ + ⍵ }
4 tryit 5
9
