Tasm  : - The Turbo Assembler (TASM) mainly PC-targeted assembler package was Borland’s offering in the x86 assembler programming tool market. As one would expect, TASM worked well with Borland’s high-level language compilers for the PC, such as Turbo Pascal, Turbo Basic and Turbo C .

Download Assembler : – From Here

• Extract it to any drive you want ex :- c: or d:

I am using it on d:  so i will provide the rest of the tutorial by using d:

What we need, is to make .asm file in Tasm Directory with an editor like notepad.

Then  follow the steps   :-

• Go to-> Command Prompt
• D:\  (The Drive in which you extract the downloaded content)
• cd  Tasm
• Tasm  Filename.asm
• Tlink  Filename
• Filename

That’s it.
