Micro operation is the level 2 operation, it is excute directly from hardware. Mainly used in provide macro instruction. Macro operation is the level more than 2 (3,4) operation, depend on your CPU structure. Sometime, we call its assembly operation. It is excute by micro operation.
Nested macro calls refer to the macro calls within the macros. A macros is available within other macro definitions also. In the scenario when a macro call occurs, which contains another macro call, the macro processor generates the nested macro definition as text and places it on the input stack. The definition of the macro is then scanned and the macro processor complies it.
Macro is a segment of code that needs to be written only once but whose basic structure can be repeated with each reference
