PSL Manual                    7 February 1983


Preface
Preface
Preface



  This Portable LISP implementation would not have been started without the
effort  and  inspiration  of  the  original  STANDARD  LISP  reporters  (A.
C. Hearn, J. Marti, M. L. Griss and C. Griss) and the many people who  gave
freely  of their advice (often unsolicited!).  We especially appreciate the
comments of A. Norman, M. Rothstein, H. Stoyan and T. Ager.

  It would not have been completed without the efforts of the  many  people
who  have  worked  arduously  on  SYSLISP  and  PSL at various levels: Eric
Benson, Will Galway, Ellen Gibson, Martin Griss, Bob Kessler, Steve Lowder,
Chip Maguire, Beryl Morrison, Don Morrison, Bobbie Othmer,  Bob  Pendleton,
and John Peterson.

  We  are also grateful for the many comments and significant contributions
by the LISP users at the Hewlett-Packard Computer Research Center  in  Palo
Alto.

  This  document  has  been  worked  on by most members of the current Utah
Symbolic Computation Group.  The primary editorial function has been in the
hands of B. Morrison, M. L. Griss, B. Othmer, and W. Galway; major sections
have been contributed by E. Benson, W. Galway, and D. Morrison.

  This is a preliminary version of the manual, and so  may  suffer  from  a
number  of  errors  and  omissions.  Please let us know of problems you may
detect.

  We have also made some stylistic decisions  regarding  Font  to  indicate
semantic  classification  and Case to make symbols more readable.  Based on
feedback from users of the earlier 3.0 PSL  release  and  manual,  we  have
decided  to  use  LISP  syntax  as  the primary description language; where
appropriate RLISP syntax also appears.  We  would  appreciate  comments  on
these and other decisions.

  Based on feedback from numerous users, this issue of the manual uses LISP
syntax  rather  than  RLISP  as  the  primary  description  language; where
appropriate, RLISP syntax also appears.

  Report bugs, errors and mis-features by sending MAIL to PSL-BUGS@Utah-20;
                                                                        Bug
                                                                        Bug
alternatively, send a message to Griss from within PSL by calling  the  Bug
function, BUG(); in RLISP.

  Permission  is  given  to  copy this manual for internal use with the PSL
