GWBASIC User's Manual

GW-BASIC User's Guide
1.4 Organization of This Manual
The GW-BASIC User's Guide is divided into six chapters, nine appendixes, and a glossary:
Chapter 1, "Welcome to GW-BASIC," describes this manual.
Chapter 2, "Getting Started with GW-BASIC," is an elementary guideline on how to begin
programming.
Chapter 3, "Reviewing and Practicing GW-BASIC," lets you use the principles of GW-BASIC
explained in Chapter 2.
Chapter 4, "The GW-BASIC Screen Editor," discusses editing commands that can be used when
inputting or modifying a GW-BASIC program. It also explains the unique properties of the ten redefinable
function keys and of other keys and keystroke combinations.
Chapter 5, "Creating and Using Files," tells you how to create files and to use the diskette input/
output (I/O) procedures.
Chapter 6, "Constants, Variables, Expressions, and Operators," defines the elements of GW-
BASIC and describes how you will use them.
Appendix A, "Error Codes and Messages," is a summary of all the error codes and error messages
that you might encounter while using GW-BASIC.
Appendix B, "Mathematical Functions," describes how to calculate certain mathematical
functions not intrinsic to GW-BASIC.
Appendix C, "ASCII Character Codes," lists the ASCII character codes recognized by GW-
BASIC.
Appendix D, "Assembly Language (Machine Code) Subroutines," shows how to include
assembly language subroutines with GW-BASIC.
Appendix E, "Converting BASIC Programs to GW-BASIC," provides pointers on converting
programs written in BASIC to GW-BASIC.
Appendix F, "Communications," describes the GW-BASIC statements required to support RS-
232 asynchronous communications with other computers and peripheral devices.
Appendix G, "Hexadecimal Equivalents," lists decimal and binary equivalents to hexadecimal
values.
Appendix H, "Key Scan Codes," lists and illustrates the key scan code values used in GW-
BASIC.
Appendix I, "Characters Recognized by GW-BASIC," describes the GW-BASIC character set.
