English Computing Dictionary
◊ I SEE NO X HERE.
I see no X here.
Hackers (and the interactive computer games they
write) traditionally favour this slightly marked usage over
other possible equivalents such as "There's no X here!" or "X
is missing." or "Where's the X?". This goes back to the
original PDP-10 {ADVENT}, which would respond in this wise if
you asked it to do something involving an object not present
at your location in the game.
