Intexpression: Any integer expression that evaluates to the number of an open file.
Use EOF to avoid errors when you attempt to get input past the end of a file. When you use the Input or Get statement to read from a file, the file pointer is advanced by the number of bytes read. When the end of a file is reached, EOF returns the value "True" (-1).
