I want to write some functions in asm and be able to use them in my C++ program.

All I've found is that I should include 'format MS COFF' line at the top of my .asm file and to write .h file with functions declarations.

Could you paste me some sample procedure (writing 'Hello world' text for example) written in fasm and declared in .h ?
I would be very glad if you wrote me how to write such procedures in .asm.

Thanks for your replies

1. 'format MS COFF' and this topic is in DOS??
2. Check: http://board.flatassembler.net/topic.php?t=3833 I posted there my project ColorLib which is a library to create colorful buttons. It is compiled as MS COFF and there's a C example too.
