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.

The three types of assembly language are: 1. Imperative: indicates an action to be performed. 2. Declaration 3. Assembler Directives
Assembler, Compiler and Interpretor
what are the elements of assembly language programming?
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.

Macros can be categorized into several types, primarily including: Function Macros: These are defined using preprocessor directives in programming languages like C and C++, allowing for code substitution during compilation. Class Macros: Common in languages like Lisp, these allow for the definition of complex code patterns and can manipulate code structures. Application Macros: Found in software like Microsoft Excel or Word, these automate repetitive tasks by recording a sequence of actions or commands. Each type serves distinct purposes in enhancing productivity and code efficiency.
