Compiling Assembly using TASM in Textpad

Continuing my last post about compiling and running assembly file, it is actually possible to easier compile and run assembly file from Textpad (unfortunately, you have to search for the Textpad text editor yourself :), and I think it is not hard to find it ;)).

Still, I am using TASM20 to compile and run the assembly file.
Assumption: The Tasm.exe & Tlink.exe files used to compile assembly file are located at C:\tasm20\TASM.

Here are the steps:
1. Create an assembly file on the same folder. The following coba.asm file is used to print character 'A'. The file can be created using any text editor.

2. Open Textpad, Go to menu Configure -> Preferences.

3. Choose Tools, then click Add.

4. Click Add -> Program -> browse for TASM.exe.

5. Click Add -> Program -> browse for TLINK.exe.

6. Click Add -> DOS Command -> type "cmd" (without quotes).

7. Notice that the added Programs and Dos command are now available in the middle listbox. Click Apply.

8. Expand Tools -> click on Tasm -> change the Parameters: $basename.

9. Click on Tlink -> change the Parameters: $basename /t.

10. Click on cmd -> change the Parameters: $basename, then click OK.

11. You will notice that the commands to compile and run the assembly file are now available on the menu Tools.

12. Open the assembly file coba.asm created on step 1.

13. To compile and run the program, press ctrl + 1, ctrl + 2, and ctrl + 3 respectively on the .asm file window.

14. After executing ctrl + 1 on the .asm file window, the result will be shown in Command Results window.

15.After executing ctrl + 2 on the .asm file window, the result will be shown in Command Results window.

16. To see the result, execute ctrl + 3 on the .asm file window. The result will be shown in Command Results window.

17. We are now done with the result of the assembly code :D

Compiling Assembly using TASM in command prompt

Are you learning Assembly language, and confused about how to compile assembly file?
TASM20 is one of assembly compilers that works with Windows XP and Windows 2000 operating system. However, it does not work with Windows 7 64-bit operating system.
If you are using Windows XP or Windows 2000, you can try the following steps to compile and run assembly file.
To download TASM20, the compiler used for assembly file, click here.

Assumption: The Tasm.exe & Tlink.exe files used to compile assembly file are located at C:\tasm20\TASM.

1. Open command prompt by pressing Windows + R, or go to Start menu -> Run, then type "cmd" (without quotes).

2. Go to the folder where the Tasm.exe & Tlink.exe files used to compile assembly file are located, i.e. C:\tasm20\TASM.

cd\tasm20\tasm

 

3. For instance, we have made an assembly file named coba.asm used to print character 'A' as following:

4. Commands used:
- To compile the assembly file, use command:

tasm <asm_filename>.asm

e.g.

tasm coba.asm

After executing the command above, an object file (coba.asm) will be created.

- To create .COM file, use command:

tlink /t <obj_filename>.obj

e.g.

tlink /t coba.obj

- To run the result (.COM file), use command:

<com_filename>

e.g.

coba

5. That's all, folks :)
