There are just some strings, but what if I want to put them in some exe's properties (in the version tab I mean). I think they'd have to be separated.

Another suggestion - shouldn't the name and the beginning of copyright be configurable
like:

Code:

__author equ 'TheBiggestAndTheGreatest'
__beginyear equ '2001'
;...
;...
copyright:
        db      'Copyright Â© ',__author,' ',__beginyear,'-',__stringyear

Now you can put it in an include and let the author and beginyear be easily changable.

EDIT:
Fixed db to equ
Thanks to vid for noticing

that won't work, because "db 'Copyright',__author"will insert address of 'TheBiggestAndTheGreatest' string behind 'Copyright' bytes, not the string. You should use something like:

Code:

__author equ 'TheBiggestAndTheGreatest'
copyright:
  db 'Copyright ',__author

But copyright is not forever, and uses system clock right? Smile

Copyrights in most countries last until 50 after the authors death. But check with your local office before taking my word for it.

If your system clock is wrong then of course the dates and times above will also be wrong.

Don't forget about the wrap around at 31 bits and/or 32 bits. Respectively 2038/01/19 03:14:08 and 2106/02/07 06:28:16.

However the calculation will be wrong after 2100-02-28 because 2100 is not a leap year.

Madis731:
You can use the strings in your exe properties also.

For example see the FASMW.ASM

Code:

  version version_info,VOS__WINDOWS32,VFT_APP,VFT2_UNKNOWN,LANG_ENGLISH+SUBLANG_DEFAULT,0,\
          'FileDescription','flat assembler',\
   'LegalCopyright',<'Copyright ',0A9h,' 1999-2004 Tomasz Grysztar.'>,\
   'FileVersion',IDE_VERSION_STRING,\
       'ProductVersion',VERSION_STRING,\
        'OriginalFilename','FASMW.EXE'

you can replace 2004 with ',__stringyear,'
