Abstract
The Decode-Encode Language (DEL) is a machine independent language tailored to two specific computer network tasks:
- accepting input codes from interactive consoles, giving immediate feedback, and packing the resulting information into message packets for network transmissin.
- and accepting message packets from another computer, unpacking them, building trees of display information, and sending other information to the user at his interactive station.
This is a working document for the evolution of the DEL language. Comments should be made through Jeff Rulifson at SRI.
