What's wrong with good old-fashioned computed-goto like:
1 testit y
2 v←hello first second byebye
3 →(y=⍳⍴v)/v
4 hello: 'hello'
5 →byebye
6 first: 'first'
7 →byebye
8 second: 'second'
9 byebye: 'byebye'
variations of which work fine as if/then/else, case statements, and
while/
Just my two cents. I've never had a problem with what Chris is saying. In
fact, I think adding if/else as described earlier would make APL not APL.
If you want if/else as described earlier, just write your own apl'ish
language.
(I wrote my first APL 41 years ago.)
