Types of macros In general, there are two types of macros: ExecutiveThese macros generate either code or data that is incorporated into the program being assembled.
Generally, an executable instruction is generated.DeclarativeThese macros produce information used by the assembly process while generating code.
z/TPF system programs use a large set of macro instructions to generate linkages or to simply generate inline code. Many of these macros are restricted to system programs because the macros are subject to change in future releases and represent an unprotected interface. A macro with an unprotected interface is called a system macro. Because some z/TPF system programs run in the application execution environment, some of the system macros also generate SVC linkages.
list out assembler directive?
For completing all the tasks, an assembler needs some hints from the programmer, i.e. the required storage for a particular constant or a variable, logical names of the segments, types of the different routines and modules, end of file, etc. These types of hints are given to the assembler using some predefined alphabetical strings called assembler directives, which help the assembler to correctly understand the assembly language programs to prepare the codes.

Assembler, Compiler and Interpretor
The three types of assembly language are: 1. Imperative: indicates an action to be performed. 2. Declaration 3. Assembler Directives
Component Macros are built in functions used to control components such as an LCD display, EEPROM, switches, serial data, etc. Macros are user created functions that help make the program more modular. As far as I can tell, there are only those 2 types.
