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.
FORWARD
The initial ARPA network working group met at SRI on October 25-26,
1968.
It was generally agreed beforehand that the runmning of interactive
programs across the network was the first problem that would be
faced.
This group, already in agreement about the underlaying notions of
a DEL-like approach, set down some terminology, expectations for
DEL programs, and lists of proposed semantic capability.
At the meeting were Andrews, Baray, Carr, Crocker, Rulifson, and
Stoughton.
A second round of meetings was then held in a piecemeal way.
Crocker meet with Rulifson at SRI on November 18, 1968. This
resulted in the incorporation of formal co-routines.
and Stoughton meet with Rulifson at SRI on Decembeer 12, 1968. It
was decided to meet again, as a group, probably at UTAH, in late
January 1969.
The first public release of this paper was at the BBN NET meeting in
Cambridge on February 13, 1969.
