# 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.
