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:
"version number" . "release number within version"
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 contains the following chapters and appendices:
.
"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 1. Introduction," which gives a general description of the PASCAL-SO
system.
"Chapter 2. Language Features," which describes the data types, control constructs, and procedure and function declarations.
"Chapter 5. Example Programs," which presents four PASCAL-SO programs,
complete with compiler listing and output.
•
"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.
