Doing nothing after output's oddly cut (2,2)
I believe the answer is:
up to
'doing' is the definition.
(as in 'what are you up to?')
'nothing after output's oddly cut' is the wordplay.
'nothing' becomes 'o' (looks like zero - 0).
'after' is a charade indicator (letters next to each other).
'oddly' indicates alternate letters.
'cut' indicates anagramming the letters.
The alternating letters of 'outputs' are 'upt'.
'o'+'upt'='oupt'
'oupt' with letters rearranged gives 'UP TO'.
(Other definitions for up to that I've seen before include "As many as, though no more" , "Engaged in doing" , "As far as a certain point" , "Capable of" , "Incumbent upon" .)
