Kip, Your response made me compare the use of 3 and 13.
f=: 13 :'%+/%y'
g=: 3 :'%+/%y'
f 2 4
1.33333
g 2 4
1.33333
f
[: % [: +/ %
g
3 : '%+/%y'
What I like best are the trees when I'm lost in the forest!
5!:4 <'f'
-- [:
+- %
--+ -- [:
L----+- / --- +
L- %
5!:4 <'g'
-- 3
-- : -+- ,:'%+/%y'

Why don't you just do
pr =: 3 : '%+/%y'
?
