Organization of this manual
This manual is organized as follows:
- Introduction, describes the
assembler language and how the assembler processes assembler language
source statements. It also describes the relationship between the
assembler and the operating system, and suggests
ways to make the task of coding easier.
- Coding and structure, describes the coding
rules for and the structure of the assembler language. It also
describes the language elements in a program.
- Program structures and addressing describes the concepts
of addressability and symbolic addressing. It also describes control
sections and the linkage between control sections.
- Machine instruction statements,
describes the machine instruction types and their formats.
- Assembler instruction statements, describes
the assembler instructions in alphabetical order.
- Introduction to macro language, describes
the macro facility concepts including macro definitions, macro instruction
statements, source and library macro definitions, and conditional
assembly language.
- How to specify macro definitions, describes the
components of a macro definition.
- How to write macro instructions, describes
how to call macro definitions using macro instructions.
- How to write conditional assembly instructions,
describes the conditional assembly language including SET symbols,
sequence symbols, data attributes, branching, and the conditional
assembly instructions.
- MHELP instruction,
describes the MHELP instruction that you can use to control a set of
macro trace and dump facilities.
- Appendix A. Assembler instructions,
summarizes the assembler instructions and assembler statements, and
the related name and operand entries.
- Appendix B. Summary of constants, summarizes the types
of constants and related information.
- Appendix C. Macro and conditional assembly language summary, summarizes the
macro language described in Part 3. This summary also includes
a summary table of the system variable symbols.
- Appendix D. Standard character set code table, shows the code
table for the assembler's standard character set.
