Hello people!
Why FASM display Errors?

Error: undefined symbol 'IDC_SIZEALL'
Error: undefined symbol 'OCR_NORMAL'



FASM code:
Code:
invoke LoadCursor,0,IDC_SIZEALL
invoke SetSystemCursor,EAX,OCR_NORMAL
    



MSDN LoadCursor Function
http://msdn.microsoft.com/en-us/library/ms648391(VS.85).aspx

MSDN SetSystemCursor Function
http://msdn.microsoft.com/en-us/library/ms648395(VS.85).aspx

-------------------------

Example code:
Code:
include 'win32ax.inc'

.data
     CURSOR_RECT      RECT    <0>
     CURSOR_POINT     POINT   <0>
     String_String    db   "API-Cursor ",0
     X_Y_SHABLON      db   "X = %d   ;   Y = %d",0
     String_CONTENER  db   256 dup (0)

.code
     start:
           invoke GetCursorPos,CURSOR_POINT
           ;-
           invoke wsprintf,String_CONTENER,X_Y_SHABLON,CURSOR_POINT.x,CURSOR_POINT.y
           ;-
           invoke MessageBox,0,String_CONTENER,String_String,0

           ;---------------

           invoke SetCursorPos,500,300

           ;---------------
           mov [CURSOR_RECT.left],450
           mov [CURSOR_RECT.top],250
           mov [CURSOR_RECT.right],550
           mov [CURSOR_RECT.bottom],350
                                                                                                                     
           invoke ClipCursor,CURSOR_RECT  
           ;---------------
                
           invoke LoadCursor,0,IDC_SIZEALL
           invoke SetSystemCursor,EAX,OCR_NORMAL

           ;&&&
           invoke ShowCursor,0
           invoke ShowCursor,1
           ;---------------

     exit:
          invoke ExitProcess,0

.end start

Fasm displays an error because IDC_SIZEALL and OCR_NORMAL are undefined symbols in equates include file. In such cases just use the numerical values from MSDN.

Code:
IDC_SIZEALL equ 32646
OCR_NORMAL equ 32512

Code:
IDC_SIZEALL = 32646
OCR_NORMAL = 32512 
    


Don't use "equ" for numerical constants.

JohnFound,

For singleton value equ is OK (I mean single fasm token). It may be OK for other cases too, if one's careful:
Code:
page    equ     4096
pages   equ     *page
        invoke  VirtualAlloc, 0, 10 pages, MEM_RESERVE, PAGE_READWRITE
