PREFACE
This manual describes the PASCAL-SO language for programming the SO SO and
SOS5 microcomputers. PASCAL-SO is based on the Pascal language invented in 1970
by Professor Niklaus Wirth of Zurich, and incorporates extensions designed to take
advantage of both the microcomputer features of the SO SO and SOS5, and the system
features of ISIS-II.
Each release of PASCAL-SO is characterized by a two-digit code in the form of:
Manual Organization

.
The PASCAL-SO language is a superset of the Pascal programming language, as
defined in
PASCAL User Manual and Report,
Second Edition, by Kathleen] ensen
and Niklaus Wirth (Springer-Verlag, 1974, Corrected Printing, 1975). This book
defines "Standard Pascal" and will be referred to in the remainder of this manual as
PASCAL User Manual. Since PASCAL User Manual is a concise reference for the
features of Standard Pascal, the programming language PASCAL-SO will be
described only by its differences from, and extensions to, Standard Pascal, the
assumption being that the reader is familiar with the contents of PASCAL User
Manual, and moderately conversant with Standard Pascal.
Chapters 1 through 3 describe the features of the PASCAL-80 language, and
Chapter 4 describes how to operate the PASCAL-SO System.
Chapter 5 presents example programs illustrating the features of PASCAL-SO. The
appendices supply reference information for all aspects of program generation,
compilation, and execution.
Audience
This manual is intended for programmers who are familiar with PASCAL. It con-
tains the following chapters and appendices:
"Chapter
1.
Introduction," which gives a general description of the PASCAL-SO
system.
"Chapter 2. Language Features," which describes the data types, control con-
structs, and procedure and function declarations.
"Chapter 3. Predeclared Procedures," which describes the predeclared procedures
and functions in PASCAL-80.
"Chapter 4. Operating Instructions," which describes how to generate, compile,
and execute a PASCAL-SO program .
"Chapter 5. Example Programs," which presents four PASCAL-SO programs,
complete with compiler listing and output.
.
•
l
"Chapter 6. Separate Compilation, Program Linkage, Relocation, and Execution,"
which gives general instructions for partitioning a Pascal program into separate
compilation units, for linking to external non-Pascal object modules and for
creating Load and Go versions of Pascal programs.
iii
"Chapter 7. Preparing Programs to Run Under
RMX/SO,"
which gives information
applicable to running Pascal programs in the
RMX/SO
environment.
"Chapter S. Run-Time Error Procedures," which gives instructions for declaring
and using user-defined error procedures.
"Appendix A. Summary of Operations," which presents, in tabular form, the
allowable operations among data types.
"Appendix
B.
PASCAL-SO Vocabulary," which contains all of the operators and
reserved words in the PASCAL-SO programming language.
"Appendix
C.
Summary of Compiler Directives," which describes the directives for
the compiler.
"Appendix D. Compiler Error Messages," which lists all errors that can be signaled
during the compilation of a Pascal program.
"Appendix
E.
Run-Time Errors," which is a listing of the error messages issued by
the system default error procedure.
"Appendix F. ISIS-II Error Messages," which is a listing of the error messages
issued by ISIS-II.
"Appendix
G.
Syntax Summary," which summarizes the syntax of legal
PASCAL-SO programs.
"Appendix
H.
Summary of Extensions to Standard Pascal," which summarizes all
extensions to Standard Pascal provided by PASCAL-SO.
"Appendix I. Implementation Details," which presents the format of the
predeclared data types in P ASCAL-80, lists certain implemtntation size limits, and
summarizes the differences between P ASCAL-80 and Standard Pascal.
"Appendix]. Pascal Reference Texts," which lists a number of books that are of
interest to the Pascal programmer.
"Appendix
K.
Directory of Release Diskettes," which lists the file directories of
both the single density and double density release diskettes.

Notation in this Manual
Throughout this manual, the following notation is used to describe the format of a
Pascal program:
Certain key words are reserved and cannot be used as identifiers. In this manual
they are in capital letters. Refer to Appendix B for a list of reserved words.
Variable names are denoted by words in lower case.
Language features which exceed Standard Pascal are shaded.
