Availability of the SETL System
SETL, a very high-level, set-theoretically oriented programming
language developed with NSF and DOE support at New York University,
is now available for distribution. As reported previously (see
Bibliography below), SETL allows algorithms to be stated in compact,
readable, relatively detail-free form. Intended uses include: (a)
fast prototyping of complex software systems; (b) experimentation
with new algorithms; (c) two-stage programming, in which
development of a procedure is followed by specification of data
structures which improve procedural efficiency; (d) education, via
student exposure to easily readable versions of algorithms.
The language has been used to implement a compiler for full Revised
Ada, a global program optimizer with advanced automatic
data-structuring facilities, several small compilers and assemblers,
and miscellaneous other applications. An executable library of
important algorithms is also being collected.
Versions of SETL are now available for CDC Cyber, DEC VAX (VMS and
UNIX), DECsystem 20 (TOPS-10 and TOPS-20), and IBM 370 (VM/CMS, MVS,
and MTS). Additional details are given below. Note that the system
is inherently large and slow-running.
The system is available at a cost of $2000 to nonacademic sites and
$100 to academic sites. The system is free to U.S. Government
Agencies. The license permits use of the system for one year, and
may be renewed. The fee includes user and installation
documentation, and best-effort maintenance for a one year period.

The current NYU implementation is written in an implementation
language called LITTLE. The following versions are quite compatible
and differ for the most part only in machine-dependent constraints
such as memory size and character set.
CDC Cyber: This version can be configured for the NOS and NOS/BE
___ _____
operating systems, using either the 63 or 64 character set. It
requires at least 200000 octal words for small programs.
DEC VAX-11: The VMS version runs under VMS V3.4. The value of the
___ ______
system configuration parameter VIRTUALPAGECNT must be at least 8192.
A version for Berkeley 4.2bsd UNIX is also available.
DEC DECsystem-10, DECsystem-20: A version for the DECsystem-20
___ _____________ ____________
running TOPS-20 is available. It should also be usable on TOPS-10
and TENEX operating systems.
IBM System/370: There are implementations for VM/CMS, MVS, and MTS.
___ __________
The CMS version requires a virtual machine of at least three
megabytes, and runs on CMS Release 6 or SP.
