MASM setup for windows (complete guide)

Hey folks! 
This post is regarding How to install MASM software (Microsoft assembler) for running assembly language codes in your PC.
In this Tutorial, I'm going to tell you how to setup 8086 microprocessor programming environment using MASM by virtually running the MASM in DOS Box.

Follow the steps:
1. Firstly, download the MASM required files from - here (It's less than 2 MB in size).
2. Extract the downloaded zip file and you will find two folders named as "DOSBox-0.74" and "8086". (see the image below)

3. Move the folder "8086" into the "C:\" directory of your PC's hard disk.
4. Now open your "DOSBox-0.74" and find the "DOSBox.exe" launcher. Launch it by a double click.

5. Now Type the exact lines found below in the DOSBox and hit enter.

"mount c c:\8086\" 

 You will find something like this,(see the image below)

   
6. Next, type "c:" and hit enter to get into C drive through DOSBox.(see the image below)

7. Now you are ready to compile and execute .asm programs.

Now,
Compiling and executing .asm programs,

1. First, write the assembly language code in notepad(any text editors) and save it exactly in "C:\8086\" with a ".asm" file extension. 

2. Now that your assembly language code is present in "C:\8086\", go to DOSBox and get into C drive using the above said steps. 

3. Compile your code using the command,

"masm program_name.asm;"

4. Link your object file of the code using the command,

"link program_name.obj;"

5. Run your code using  commands:
"program_name.exe" to run it normally.
or type,
"afdebug program_name.exe" if you want to debug the code in the debugging
screen.

See the screenshots below, 

1. Running normally using "program_name.exe"

2. Running in debugging mode using "afdebug program_name.exe"

That's it. Enjoy microprocessor programming. Cheers!
