# Boolean Values in Ini Files > [HTML Version](booleanargsininifiles.htm) Initialization file options that take a Boolean argument are somewhat internationally minded. The table below shows first-letter responses and A-Shell interpretation as true or false. | **True** | **False** | |------|------| | T (True) | F (False,Falso) | | Y (Yes) | N (No,Non) | | 1 | 0 | | ON | OFF | | Sí | | | Si (Sim) | | | OU (Oui) | | | Al (Allineare) | | | V (Verdad,vrai,verdadeiro) | | Any other starting letter will be checked against the current LDF (language definition file) to see if it matches the single-character yes or no definitions.
