Original: Systems based on ASCII or a compatible character set use either LF ( Line feed , ' n ' , 0x0A , 10 in decimal ) or CR ( Carriage return , ' r ' , 0x0D , 13 in decimal ) individually , or CR followed by LF ( CR+LF , 0x0D 0x0A ) .
Simplified: On some systems , such as the Unix family , it also returns to the beginning of the line , like the carriage return character .
