This is admittedly quite a stretch, but....
One of the reasons why I first had the idea that Pynchon might think of a text as something analogous to a software program came from David Cowart's comments about Pynchon's prescient views about technology.
According to Cowart, Pynchon was quite a intense little scientific amateur, as can be seen from his keen treatment of the subject of entropy. I noticed myself that Pynchon likes to use scientific metaphors (like when Oedipa views the city of San Narciso as looking like a giant printed circuit).
So ... it made sense to me that Pynchon might, with his interests in science, might make the jump into information theory, and view the text as kind of a "scout vehicle" with which the reader could explore a logoverse!
