Check out the Turing Oddities contest in the [Contest] section if you want to set a variable back to having no value. You should probably ignore the above comment, as it is pretty difficult. You should probably just set it back to 0, or a null string, etc. |

dani, you can reuse variables without setting them back to null. For instance, if i have a variable called variable and i use it in one context that manipulates it to the value 5, i can then ignore this value if i want to set it to another value. By declaring a variables value like this: variable := value you make that variable equal to that value. Unless you did something stupid like try to make it a value of the wrong type. |
