Hi Jürgen,
> Interestingly, my *APL2* reports *DOMAIN ERROR* on
*0 +/ 99*
*Odd. You should mention that in the APL2 forum. Perhaps you need a later
service level.*
*There's still one minor inconsistency between APL2 and GNU APL on that
expression. *
*≡ reports a depth of 4 for the result in APL2 and a depth of 3 in GNU
APL. I have no idea why. APL2 appears to be doing an extra enclose on the
elements of the array.*
*In my APL2, enclose of a simple scalar (a single character or number), is
a no-op. However, enclosed arrays are not simple scalars and can be
enclosed again, increasing their depth by one.*
*This is different from GNU APL, which appears to no-op all encloses of
scalars.*

Which one of these is "right" is a philosophical question.
