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 ⍬.
