Uhrwerk: I fixed that problem with #include but I still get a black screen. Also, it isn't just this script that gives, its anything that I try and make. Is is a bug in a7 or the free Lite-C version? Or could there be something wrong with my machine? I am using an Acer Notebook with a processor speed of 1.73GHz, 1014 MG of RAM, and a 32-bit operating system. I have Windows Vista.
