The Assembler is a flexible tool for writing programs,
but every operating system imposes certain conventions and restrictions
on the programs that are intended to run on that system. This chapter
discusses the conventions that must be understood in order to write
assembly language programs and procedures for the PA-RISC instruction
set on the HP 9000 Series 700 and 800 HP-UX operating system. Several
Assembler directives are mentioned in this chapter to place them
in a meaningful context. A full discussion of these directives is
in Chapter 4 “Assembler Directives and Pseudo-Operations”.
