Edit: added "code" tags - fbk

i`m trying to print the perfect numbers !!!

It's an imperfect world!

Are you trying to assemble this with Nasm? Won't work - your code would need several changes. That can be done, but it might be easier to assemble it with an assembler that it's intended for. I would suggest Jwasm (just because I don't like MS too much). If you wish to convert it to something compatible with Nasm, we can probably help with that.

i want to assemble it with tasm !!!!

[Frank Kotler]

Okay. Got a manual for Tasm? Maybe should read it. The only thing I see that might cause an "unexpected end of file" is that Tasm expects you to end segments. I'm not sure if that applies to the "simplified segment directives" you're using. Maybe you can find an example that assembles properly to compare against?

I have two suggestions.

1. When you post code on the forum, please surround it in [CODE][/CODE] tags. It makes reading your source a lot easier.

2. Since your code looks fine and since TASM is basically obsolete. Try opening your file in Notepad and use "Save As..." and make sure that you save the file as an MS-DOS text file. Modern OS's like to use Unicode whenever possible and that can make things difficult for older software which doesn't support it.

Okay, I stuck "code" tags around it.

Just to follow up... Deeband posted this question to Stack Overflow (very active board!). After getting similar advice to here (ends), he announced that it was "solved - it was a problem with my computer." - quite possibly the Unicode problem you mention. In any case, it can (conceptually) be marked "solved". (I don't think his code is gonna work, but it least it assembles)

Ah okay. Thanks for the update  . I've been away for a bit so I didn't realize this was already an old thread.
