 <source lang="bascomavr">
Ff =Freefile()' get file handle
Open "test.txt" For Input As #ff ' we can use a constant for the file too
Print Lof(#ff); " length of file"
Print Fileattr(#ff); " file mode"' should be 1 for input
Do
LineInput #ff , S ' read a line
' line input is used to read a line of text from a file
Print S ' print on terminal emulator
Loop Until Eof(#ff)<> 0
'The EOF() function returns a non-zero number when the end of the file is reached
'This way we know that there is no more data we can read
Close #ff
