Network Working Group A. G. Nemeth
Request for Comments: 43 M.I.T. Lincoln Laboratory
8 April 1970
Proposed Meeting
On Friday, 8 May 1970, at 9:30 AM a meeting at M.I.T. Lincoln
Laboratory is proposed. A description of LIL (Local Interaction
Language) for the TSP (Terminal Support Processor) system will be
presented.
The purpose of the TSP system is to provide a flexible I/O
capability for network users. In order to achieve maximum flexibility,
the system is user-programmable in an interpretable language called
LIL.
LIL has the appropriate primitives for manipulating tree
structures (for interactive graphics) as well as message-oriented
I/O. The general purpose portion of the language is used to specify
the I/O handlers and the display structures.
A discussion of the problems of handling interactive programs
over the ARPA network will follow.
This conference is intended as a working group and each host
should send as few or as many individuals as are actively
interested. A working document on LIL will be mailed about a week in
advance to interested individuals.
Anyone interested in attending and/or receiving the documents
should contact A. G. Nemeth (x7354) or J. Forgie (x7173) at
M.I.T. Lincoln Labs, Lexington, Mass. 02173, (617) 862-5500.

§1Meeting Proposal
The RFC announces a meeting at MIT Lincoln Laboratory on Friday, May 8, 1970, at 9:30 AM. The purpose is to present the Local Interaction Language (LIL), a system designed to provide flexible I/O capabilities for network users.
Each participating host site is invited to send as many or as few interested individuals as they wish. The meeting is framed as a working group session rather than a formal conference.
A meeting is planned to talk about making the network work better for programs that draw pictures and take user input.
§2The TSP System and LIL
The Terminal Support Processor (TSP) system aims to provide maximum flexibility in how network users can input and output data. To achieve this flexibility, TSP is user-programmable in an interpretable language called LIL (Local Interaction Language).
LIL has primitives specifically designed for two tasks: manipulating tree structures for interactive graphics, and handling message-oriented input/output. The language combines these capabilities with general-purpose programming constructs to let users specify both the I/O handlers and the display structures their application needs.
LIL is a language that lets you program how the network program talks to you, with special tools for drawing and receiving user input.
§3Interactive Programs Over the Network
A key discussion topic at the meeting will be the challenges of running interactive programs over the ARPA network. Interactive graphics and real-time user input present different constraints than batch data transfer.
Interested parties should contact A. G. Nemeth or J. Forgie at MIT Lincoln Laboratory (contact info provided in the RFC). A working document on LIL was to be mailed about a week before the meeting to interested individuals.
When programs let people draw and click things, the network has to be fast enough. This meeting will talk about how to make that work.
