Welcome to the 'well that's embarrassing' club. We have all been there.
For the 3 arguments you would like to use, I generally use one of two
techniques.
For explicit
area=: 3 : 0 NB. Area of rectangle - y is width and height
'w h'=. y NB. multiple assignment to w and h
w*h
)
or tacit
areat=: (0{ ]) * 1{ ] NB. you control the way you handle the multiple argument
string
These could be defined dyadically, but the technique becomes necessary when you
have three arguments and only monadic and dyadic verbs.
If I have missed with this advice, I am sure I will do my own 'well that's
embarrassing' moment. In this group it feels more like a teachable moment. :)
Cheers, bob
