Problems with RunTimeError()

I'm assuming Logo_Pointer is a global variable...

However, a more tidy version would be...

Function LoadBitmap(filename$)
	bitmap = LoadImage (filename$)
	If bitmap = 0 Then RuntimeError "Failed to locate & load "+filename
	Return bitmap
End Function

and then you'd use

logopointer = loadbitmap("klogo.png")

And they'd be no need for globals and the function is more flexible.
