Dr. Tony Earrwig: There is no record in SHRDLU's memory of any block
being dropped. The answer routines have special checks for this type of
"loaded question" which presupposes things which aren't true.- Eta Din: is there anything to the right of the red pyramid?
SHRDLU: YES, FOUR THINGS: THE BOX, THE RED CUBE, THE BLUE
PYRAMID AND THE BLOCK NAMED SUPERBLOCK.
Dr. Tony Earrwig: Once an object has a name, the name is used to help
identify it in responses. - Eta Din: thank yOll.
SHRDLU: YOU'RE WELCOME!
Dr. Tony Earrwig: SHRDLU's grammar is written as a procedure, which
gives SHRDLU the capability to carry out special sorts of parsing for
idioms.
