There are a number of problems here, the registers are 64 bit, there is no build information (which assembler and linker), no include files even though it looks like you are trying to call MSVCRT functions or VS runtime functions.
Try telling us more about what you are trying to do and with what tools you are trying to do it with and someone may be able to help you.
Thank You... what i am try to do is get user input as a decimal then convert it to binary. I really need help
The problem is we are not magicians, we don't know what assembler you are using, what include files you are using or what libraries you are using. The code you have posted is not complete and there is no way to work it out. Until you can tell us enough to comprehend what you are doing, there is nothing we can do to help you.
I have now done this but its still giving me missing operator expression

Thank you very much its workin!!!
So How can you now allow user to input a value?
not at all!
Processing the command line or read about the Dialogs.
You have the same bad English as me. What country are you from?
HAHAHAHAHAHA Am from Zambia and Yourself?
I'm from Russia. There is winter in our contry now

Very nice scenery.
Is the bear sleeping now?
Hi, Timo!
Wild bears are already asleeping in forest, and the pet cub sleeps only at night. He lives in warm and eats every day, he doesn't sleep for the whole winter and he not needed saves fat reserves until spring

look masm32\examples\resdlg
The easiest, quick and dirty way to input an integer is probably scanf but it has its quirks, namely it is not interactive - i.e it reads the whole line before looking for what you inputted.
Official language in Zambia is English, lol.
Can you help me please?
I have commented your code, and changed a few lines. Study it carefully, especially the adc instruction. Btw it would really help if you could explain in a few words what you are doing here. This looks like homework, right? What are you studying?
