Programs
end up as numbers
in mailboxes, also!
in mailboxes, also!
Programs are stored the same
way, as a buffer of numbers. A program that reads someone’s last name and repeats it to
them is compiled into a series of instructions
that Norman understands.
Each instruction has a unique
number. For example,
•23 = “Copy the number from
the next mailbox and hold that piece of paper
in your left hand.”
•188 = “Put the piece of paper in your left hand into the
mailbox with the box number written on the
piece of paper in your right hand.”
