The GetClientRect compiles with an error. WHY?

.const
RECT
rcClient       STRUCT
left         db   360
top          db   160
right        db   560
bottom       db   200
rcClient       ENDS

GetClientRect,[hWnd],addr rcClient

WndProc:
    FRAME  hWnd,iMsg,wParam,lParam,hPen,xx,yy,ww,hh

Error!
Line 226 of assembler source file (xxxxxx.asm):-
Unknown mnemonic, instruction, redefinition or directive:-
GetClientRect,[hWnd],addr rcClient

RECT has 4 dword members. It won't work with "db". Besides, GetClientRect writes to the rect: difficult to a constant.

That's true, but there should also be "invoke" before the function name.

Thanks fellows.
I have an extraordinary way of missing the obvious. :(
