Opens a file.
fileopen <file handle> <filename> <append flag>
Opens a file specified by <file name>.
If the file does not exist, it is created and then opened. If the file is successfully opened, the file handle is returned in the integer variable <file handle>. Otherwise, <file handle> is set to -1.
If <append flag> is zero, the file pointer is set to the beginning of the file. If <append flag> is non-zero, the file pointer is set to the end of the file.
Also, the file is opened in the binary mode.
