Title: error A2206: missing operator in expression
Post by: gelatine1 on April 22, 2014, 05:46:28 AM

What is wrong with my code ? I am getting the error for the line 'integer db 0y01010101' where I am simply trying to define a binary number.
This is my code:

Code Select


.386 
.model flat, stdcall 
option casemap :none 
 
include \masm32\include\windows.inc 
include \masm32\include\kernel32.inc 
include \masm32\include\masm32.inc 
 
includelib \masm32\lib\kernel32.lib 
includelib \masm32\lib\masm32.lib 
 
.data 
	integer db 0y01010101
.code 
	
start: 
	
	lea eax,integer
	push eax
	call StdOut 
	
	push 0
	call ExitProcess
 
end start

According to that page i should use the 0y prefix and it doesnt even say anything about the b suffix. Why is that ? Is it only working for other assemblers ?

You're reading debugger reference
A few days ago qWord uploaded MASM reference . You may download it here (http://masm32.com/board/index.php?topic=3116.msg32323#msg32323).

For MASM y and b can be used as suffix for binary numbers, whereas the first one is independent of the current radix setting.
e.g.: 101010y
