INTRODUCTION AND HISTORICAL NOTES _________________________________
This description is a user’s guide for the double-precision version
of SLIP installed in MTS. This version of SLIP is compatible with
FORTRAN IV and can be used in conjunction with programs that are able to
call FORTRAN routines. Most of this version of SLIP is written in
FORTRAN with a small portion, the SLIP primitives, written in 360/370-
assembler language. Complete citation for the references noted are
included in the last subsection "References."
The definitive paper on SLIP by Weizenbaum (3) was published in 1963.
That paper is not a user’s guide, but achieves a general description of
SLIP by defining the available data structuring functions together with
implementational details. The paper is novel in that it includes a
listing of the FORTRAN code. Two letters to the Communications of ACM _______________________
(4,5) add information for SLIP implementors and users. Subsequently a
book by Findler, Pfaltz, and Bernstein (6) that is a readable and useful
reference for users was published. Another book by Waite (7) offers
constructive criticisms, some of which are employed in this implementa-
tion. However, these are directed mainly to the student of high-level
list-processing systems for FORTRAN IV and thus perpetuate the policy of
Weizenbaum’s paper. User functions, together with implementational
details, are presented.
This description attempts to minimize emphasis on implementational
details and concentrates instead on the user functions.
The literature indicates that many versions of SLIP, for a variety of
machines, exist. Here, every attempt has been made to maintain the
spirit of the original version of SLIP and the names and assignments of
its functions. This attempt has not been entirely successful. New or
alternate functions were required for this implementation. Care has
been exercised to state where deviation from the original version was
necessary. Essentially deviations arise from limitations obtained from
the IBM System/360/370 32-bit word size.
