Hi,

I was writing a procedure using the 'proc' instruction with the ouput set to plain binary, however the assembler gave an error at the 'proc' keyword, saying that it is an illegal instruction.

Is there a workaround? Am I doing something wrong?

FYI, the code looks something like this:

format binary

proc Hello
int 0x10
endp

proc and endp are macros; not x86 instructions, so you'll need to include the appropiate macro package.
