Simulation Using MASM

Simulation Using MASM (Microsoft Assembler)

Need for Assembler:

•  Learn how computer works at low level.
•  Write device drivers
•  Optimize program for speed & size.
•  Debug, hack & dissect other programs
•  Bootstrap new computer system
•  Communicate with input, output directly
•  Write utilities in HLL using features not available in those
•  languages.

MASM for microprocessor can be used in 2 ways: 

1. With models that are unique to a particular assembler 
2. With full segment definition that allow full control over the assembly process & are universal to all
     assemblers.
