Greetings,
APL-1 did not allow functions to be defined with [ and ] in the header. I've seen it done in GNU APL as follows:
∇fun[⎕]∇
∇
[0] fun[x]y
[1] x
[2] y
∇
I understand what is going on, but I was looking for it in the APL-2 manuals. I couldn't find it in any of the IBM manuals (and the spec is unreadable to me). So, my question is, where in the IBM APL-2 Language Manual is it shown? Any place else?
Thanks.
Blake
