your system. To be sure that your system is set up properly, consult theowner's manual that came with your system and the user's manuals for anyadditional equipment you are using.Where to Find What You NeedThis manual is divided into five parts, preceded by this Introduction. Eachpart has its own Table of Contents and List of Figures and Tables. The firstpart contains the hardware and startup information needed by everyone,and the last part contains the Bibliography, Glossary, and Index for allpreceding parts. Each of the parts in between has its own appendixes. Inthis regard, the three major parts resemble stand-alone volumes; having oneglossary and index common to all parts, however, makes each of them apart of the larger, self-contained volume.It is important to read this Introduction to learn whetherApple II Pascal 1.3 is the appropriate product choice for you and to getacquainted with this manual and how it is arranged.Read Part I, Getting Started, to learno About hardware requirements and possible system configurations withPascal 1.3;o How variations in hardware might affect your use of Pascal;o How to start up your system with the Pascal disks that come with thispackage;o How to refer to I/O devices;o How to create working disks that suit your system and your needs.Part II, Program Preparation Tools, describes the Pascal system and themechanics of using each of the software tools required to prepare a Pascalprogram. Each of these program preparation tools is itself a programavailable on the Pascal 1.3 system disks. The major components of thePascal system are the Pascal Filer, Editor, Compiler, Assembler, Linker, andApple Pascal utility programs, most notably the Librarian program. Part IIdescribes all the details needed too Create and manipulate files;o Enter and edit text;o Compile Pascal source files;o Create an assembly-language program and link it to a Pascal program;o Create and use library files;o Format disks;o Configure an external terminal into your system.ivIntroduction to Pascal 1.3
Although the descriptions of the Pascal Compiler and Assembler summarizethe available Compiler options and Assembler directives, they do notdiscuss how to implement these in programs. Part II gives no instruction inthe writing of Pascal programs or 6502 assembly-language routines. If youare interested in integrating specific rules of Pascal syntax with thisoverview, you will need to move back and forth between Part II and Part III.If you want to learn more about 6502 assembly-language programming, seethe Bibliography in Part V. All error messages are described in the lastappendix of Part II.Part III, the Language Manual,o Explains the details of how to write Pascal source text using correctsyntax;o Describes all the rules of the Apple II Pascal language;o Explains the structure of the language and compares it briefly with otherlanguages;o Defines the Apple Pascal vocabulary;o Includes advanced programming techniques.When you want to compile any part of a program, refer to "The Compiler" inPart II; when you want to link program pieces, refer to "The Linker" inPart II; to put a Program Unit into a library, refer to "The Librarian" inPart II. Pascal programming techniques are discussed exclusively in Part III.Part IV, the Technical Reference, describeso The technical details of Apple Pascal memory usage;o The internal structure of Pascal codefiles, textfiles, and disk directories;o The structure of the Pascal P-machine;o The P-machine instruction set.Most users will rarely have an occasion to use Part IV, but some may beinterested in the P-machine or the internal structure of codefiles.Part V contains the Bibliography, Glossary, and Index for all parts of thismanual. The Bibliography lists references for both Pascal and 6502 ·assembly-language programming, as well as sources of more general butrelated information. Part V concludes with a list of other licensed Appleproducts.To find out about the Apple developer relations program, see the back pageof Part V of this manual for information about whom to contact.About This Manualv
