Analysis of Macroprocessor with Nested Macro Calls in Sample Code

This document presents an in-depth analysis of a macroprocessor featuring nested macro calls, using a specific code example. The macroprocessor supports macro variables and provides a detailed breakdown of the macro definitions, actual parameters, and the resulting output. It systematically illustrates how the nested calls are managed within the processing flow, utilizing a structured format to represent the variables and operations involved. A comprehensive overview of formal parameters, stack management, and the resulting assembly-like code is also provided for clarity.
