Up until now, we mostly considered macro instructions to be some sort of replacement for procedure calls, although I believe it would be correct to refer to them as convenience instruments for simplifying the writing and maintenance of the code. In this part of the chapter, we will see some so to say built-in macro instructions--assembler directives--which may virtually be divided into three categories:
- Conditional assembly
- Repeat directives
- Inclusion directives
Additional categories may be present depending on assembler implementation. You should refer to the documentation of the assembler you are using for more information.
