masm32 code shows error "A2206"

Question

the following code segment is supposed to walk the InInitializationOrderModuleList inside the PEB and return the base address of kernel32.dll. However, when I try to Console assemble and link the following code I get the error stating that there is a missing operator in expression.

.486                                                     
option casemap :none                    

include \masm32\include\masm32rt.inc

.code
start:
call main
exit

main proc
mov eax, large fs:30h
mov eax, [eax+0Ch]
mov esi, [eax+1Ch]
lodsd
mov eax, [eax+8]
print str$(eax)
ret
main endp

end start

So, I changed the line as :-

mov eax, fs:30h

and the error I get is error A2108: Use of register assumed to ERROR. What am I doing wrong?

Answer 1

Just figured out, adding assume fs:nothing solves the problem.
