FileOpen $FO_CREATEPATH doesnt work

The FileOpen help file gives these options:

[optional] Mode to open the file in.
Can be a combination of the following:
    $FO_READ (0) = Read mode (default)
    $FO_APPEND (1) = Write mode (append to end of file)
    $FO_OVERWRITE (2) = Write mode (erase previous contents)
    $FO_CREATEPATH (8) = Create directory structure if it doesn't exist (See Remarks).
 
and some more options.
 
But this simple code just doesn't work:
dim $hFileOpen
$hFileOpen  = FileOpen ( "c:testtest.txt", $FO_CREATEPATH )
If $hFileOpen = -1 Then
        MsgBox($MB_SYSTEMMODAL, "", "An error occurred when creating/opening the file.")
        Return False
    EndIf
FileClose($hFileOpen)
 
 
Is the FO_CREATEPATH mode not implementen? Found it weird nobody on the forum ever encountered this...

Only $FO_CREATEPATH implies $FO_READ, because of the value 0. You have to use $FO_CREATEPATH + some write mode flag.

Programming today is a race between software engineers striving to
build bigger and better idiot-proof programs, and the Universe
trying to produce bigger and better idiots.
So far, the Universe is winning.
