How to work with WinAPI in a FASM function?

Question

assembler

It is necessary to use WinAPI functions in a function written in FASM, but the line

format MS COFF

does not allow compilation with WinAPI functions. Tell me how to do it.

format MS COFF
include 'include\win32w.inc'
public drawLine as '[email protected]'

section '.data' data readable writeable
_class TCHAR 'FASMWIN32',0
_title TCHAR 'Win32 program template',0
_error TCHAR 'Startup failed.',0

wc WNDCLASS 0,WindowProc,0,0,NULL,NULL,NULL,COLOR_BACKGROUND,NULL,_class

section '.code' code readable executable     ; ?????? ????

proc drawLine, x:DWORD, y:DWORD
    invoke  GetModuleHandle
    mov [wc.hInstance],eax
    invoke  LoadIcon,0,IDI_APPLICATION
    mov [wc.hIcon],eax
    invoke  LoadCursor,0,IDC_ARROW
    mov [wc.hCursor],eax
    invoke CreateSolidBrush, 0xFFFFFF  ; ????? ???
    mov [wc.hbrBackground], eax
    invoke  RegisterClass,wc
    test    eax,eax
    jz  error
