Intel XENIX 286 Programmers Guide (86) - Tenox.tc

CHAPTER 1
INTRODUCTION
This manual describes XENIX 286 Extended System commands used for developing and
maintaining programs. These commands support program development, checking,
debugging, maintenance, and version control.
Prerequisites
This manual presumes that you understand the C programming language and basic
programming concepts. This manual also presumes some knowledge of XENIX or UNIX
and the standard shell sh.
Manual Organ ization
This manual contains the following chapters and appendixes:
1. Introduction: manual overview, prerequisites, organization, and notation.
2. cc: C Compiler: the cc command for compiling C programs and assembling and
linking the resulting modules.
3. lint: C Program Checker: a program that checks C programs for syntactic and
semantic errors.
4. make: Program Maintainer: a program that automates the generation of program
files, independent of the programming language or programming tools used.
5. SCCS: Source Code Control System: a set of commands to manipulate multiple
versions of a single program or document, stored in a single file instead of in
separate files for each version.
6. adb: Program Debugger: a program for debugging C or assembly language
programs.
7. as: Assembler: the assembler used to assemble separate assembly language
programs.
8. csh: C Shell: a command interpreter that provides greater flexibility and more
power than the standard shell sh.
9. lex: Lexical Analyzer Generator: a program that produces another program,
called a lexical analyzer, that breaks up an input stream into "tokens," using rules
specified to the generator.
