Hello...

I'm a newbie and I need to learn assembly language. I already read some tutorials (also the one of this page) and I think I understand about handling bytes and words. But however I couldn't find further exmaple for variable managment like DWORD type or something else.

For example: How can I change the value of a declared dword? Is this the right way?
mov dword [myvar],(10*1000+...anything)

How can I now for example print this DWORD on the screen? I know that I can print something through int 21 if I set AH to 9 and DX to the data that should be written. However I don't know how to used that now for DWORD...

If you can help me or just know a good tutorial about, please answer on this post. Smile

Thank you

you have to convert it to a string before you can print it to the screen.

Welcome to reinventing the wheel Smile I am sure someone else has an itoa code that would work for this...

Well thank you but as a newbie I can't handle this answer much... Maybe some sample? And what about the moving values....

Thank you

You don't need () when moving values. The example you specified for mov should work.
