HOW TO RUN MASM ON UBUNTU/WINDOWS

Firstly, Download MASM (click on the link, goto "File" and choose "download") and extract it from zip.

1. Create a folder named 'splab' in the home folder
2. move (cut-paste) the extracted "MASM" folder inside splab folder in home.

Using DOSBOX for MASM (FOR UBUNTU):
1. Open terminal, type dosbox. (If not found, install it by typing "sudo apt-get install dosbox".
2. Run the command dosbox from terminal
3. At Z prompt type
        'mount c  /home/yourLoginName/splab'
4. Type C:  ,you will get C prompt
5. Change directory to MASM to assemble masm programs (cd MASM)

How to Assemble MASM program:
1. masm program.asm         (create .obj file)
2. link program.obj               (create .exe file)
3. program                           (execute your program)

Test if MASM is working fine:
( c2e1.asm is an example program included in the folder )
1. open terminal, type dosbox
2. in dosbox type, mount c /home/yourLoginName/splab
3. type, C:
4. type, cd MASM
5. type, masm c2e1.asm
6. type, link c2e1.obj
7. type, c2e1 to run it

Basic Programs : Language C

• Replicating dos copy command
• Display file attributes
• Reverse file content

• To-send-n-numbers-from-parent-process
• To-send-n-strings-from-parent-to-child
• To-send-back-prime-numbers-to-parent
• To-send-palindrome-back-to-parent

• Shared Memory: Child Process finds the largest and Smallest Number
• Shared Memory: Display names in alphabetical order in child process
• Producer-Consumer Problem

• TCP Client-Server Chat Session
• UDP Client-Server Chat Session

• X sends N numbers to Y who select prime numbers and send them to Z. Z send the sum of primes to X who displays the result. Implement IPC using pipes. X,Y,Z are processes.(2013)
• Process X gives a file name and value n to process Y. Y has to copy first n lines of file into a new file and sent the file name back to X who display the content of new file. Implement using pipes.(2013)
