Label or instruction expected at start of line

when trying to compile this.

global start
extern GetCommandLineW
extern GetModuleHandleW
extern ExitProcess

[SECTION .code use64]

start:
push 3 ; nCmdShow SW_MAXIMIZE who needs this argument????????
call GetCommandLineW ; win32 API
push eax ; lpCmdLine
xor eax, eax
push eax ; hPrev nobody need this argument.
push eax
call GetModuleHandleW; win32 API
push eax ; hInst
call WinMain ; call WinMain with 4 arguments on the stack
exit:
push eax ; error code
call ExitProcess ; win32 API
; WinMain(HINSTANCE hInst, HINSTANCE hPrev, LPSTR lpCmdLine, int nCmdShow)
WinMain:
; do some useful things here
xor eax, eax ; return 0, everything went well
ret 16 ; restore the stack, pop 4 arguments

Hi Andy,

Possible that your editor (notepad?) is defaulting to utf-8 or
something? You may need to instruct your editor that you need ascii text.

I don't think it should cause an error, but ".code" is not one of the
"known" section names in "-f win32". Try "section .text". Also seems to
be some confusion whether you're doing 32 or 64 bit code...

Best,
Frank
