I'm using these verbs a lot. Put them in a
utility.ijs file that you tend to run during any
session. They basically, ease the splitting of lines
when you want to enhance readability, quickly cache a
computation that takes some time, or just want to make
sure the intermediate step produces what you want.
up=: 3 :'UP=:y' NB. temp result cache
initifundef =: (, ('_'&([,],[))@(>@(18!:5)@(0&$)) )
'UP' initifundef i.0 [ 'UP2' initifundef i.0 [ 'UP3'
initifundef i.0 NB. saves current values if reloaded.
up3=: 3 :'(UP=:y) [ (UP2=: UP) [ (UP3=: UP2)'
up3 +/ i.10
45
up3 +: UP
90
UP2
45
up UP2 , UP
45 90
up UP2 , UP
45 45 90
the up3 verb caches the last 3 results and slides them
along to UP, UP1, and UP2. the up verb caches the
last result only into UP. I find using these inside
definitions useful too, but I often end up clobbering
over toplevel caches.
