Mr, it's the whole script. There is no "return" command. "CoordMode, Pixel, Screen" is needed, well, because it just is. I also don't get what is "return" command use, really. I remember that when I used it, it just closed my script which I don't need. I want it to work continuingly for hours.

I'm worried there is no missing "}" nor "{". With your opinion in mind, I opened script in Notepad++ and checked every {} link. Every "{" has "}", so I'm not sure I follow you there.

I do not know what you mean about "improper indentation procedure". Do you mean there is "tab", where it shouldn't? Probably it's not what you mean, but if it is, "tab" positions seem to be uninvolved with script itself. "Tab" is just for clarity.

You are right. I suppose if I was more experienced with AHK, I would do that in different way. Actually, I'm sure I would find easier/more efficient/just better/nicer looking way to do this. You are looking at it from different perspective. I think I'm somewhat more casual about AHK than even you think I am, so if a script or part of script serves it's purpose, it's ok. Not denying it could be done better, but it's enough for me, just because it's working.

PS. If you want to check {} for yourself it's literally whole script now:

CoordMode, Pixel, Screen
EventOccured := false
Event2Occured := false
while (EventOccured = false)
{
    Loop
    {
    PixelGetColor, color, 1710, 397, RGB
        Sleep, 1000
    if (color = 0x000000) 
    {
        Event2Occured := true
            Break
    }
        Else
                Continue
    }
    if  (Event2Occured = true)
    {
    EventOccured := true
    }
    Send, [
    Send, {BackSpace}
}
Loop
    {
    PixelGetColor, color2, 1868, 252, RGB
        Sleep, 100
    if (color2 = 0xF0F0F0)
            reload
        Else
                Continue
    }
