Computational Representation —
The parse graphs we've been looking at so far bring us
one step closer to the pointer graphs it takes to make
the above types of maps and trees live in computer memory
but they are still a couple of steps too abstract to detail
the concrete species of dynamic data structures we need.
The time has come to flesh out the skeletons we have
drawn up to this point.
Nodes in a graph represent “records” in computer memory.
A record is a collection of data which can be conceived
to reside at a specific “address”. The address of a record
is analogous to a demonstrative pronoun, a word like “this”
or “that”, on which account programmers call it a “pointer”
and semioticians recognize it as a type of sign called an
“index”.
