PSL 3.1 AVAILABILITY
PSL (Portable Standard LISP) is a new LISP implemented at the University of
Utah as a successor to the various Standard LISP systems we previously
distributed. PSL is about the power, speed and flavor of Franz LISP or
MACLISP, with growing influence from Common LISP. It is recognized as an
efficient and portable LISP implementation with many more capabilities than
described in the 1979 Standard LISP Report.
PSL's efficiency and portability is obtained by writing essentially all of
PSL in itself, and using an optimizing compiler driven by tables describing the
target hardware and software environment. A standard PSL distribution includes
all the sources needed to build, modify and maintain PSL on that machine, the
executables and a manual. PSL has a machine oriented "mode" for systems
programming in LISP (SYSLISP) that permits access to the target machine about
as efficiently as in C or PASCAL. This mode provides for significant speed up
of user programs.
PSL is in heavy use at Utah, and by collaborators at Hewlett-Packard, Rand,
Stanford and other sites. Many existing programs and applications have been
adapted to PSL including Hearn's REDUCE computer algebra system and GLISP,
Novak's object oriented LISP dialect. These are available from Hearn and Novak.
PSL systems available from Utah include:
VAX, Unix (4.1, 4.1a) 1600 BPI Tar format
DEC-20, Tops-20 V4 & V5 1600 BPI Dumper format
Apollo, Aegis 5.0 6 floppy disks, RBAK format
Extended DEC-20, 1600 BPI Dumper format
Tops-20 V5
We are currently charging a $200 tape or floppy distribution fee for each
system. To obtain a copy of the license and order form, please send a NET
