Re: [Bug-apl] Determining data type...

Never heard of χ.  Not on my keyboard.  Sounds like I need it.  What is the U code for it?  Is it U+03a7 or U+03C7?

Thanks.

Right. I was thinking of χ, which apparently is called chi.

You're probably refering to ⍬.  This is not a theta.  This symbol
is called zilde and it should look like zero with superimposed
tilde.  It's not specifically related to lambdas.
Zilde stands for a numeric vector of zero length (just like '' is
a character vector).  You can write (0⍴0) instead of ⍬.
