Very nice sire. I couldn't have done better myself! Great stuff.

it's fake. code is not asm, it's macros

Nice. But in fact it's just a macro which creates a very long string contains the song's lyrics. So it looks like 'print("99 bottles of beer on the wall...."' in C.

hell0g and mix_mix - It's not fake.

The prime reason to write this code was to demonstrate Tasm metaprogramming abilities. You should review the code and take notice on this: the stanzas are printed twice. First one during the compilation and second one during the usual run from the command prompt.

So, yes, this program is macros. The result is one big string. But this string is displayed during the compilation! That was the reason and intended one!

You are neglectful, guys.

@vladimir: While I agree with you that hell0g and mix_mix are being slightly harsh,
the fact remains that your code (IMO it's legitimate code) doesn't handle the
singular case of "1 bottle" correctly and should be revised accordingly. Good luck!
