Notes

Galzohar
If the condition is nil then neither the "then" nor the "else" section get executed, but the script will proceed with no error messages.

Example code: hint "script started"; //will get executed if (nil) then { hint "true"; // will never get executed } else { hint "false"; // will never get executed }; sleep 3; hint "script ended"; //will get executed Tested on Arma 2 vanilla 1.05.

Any variables you declare within the body of an if/then statement (ie between the curly braces) are local to that 'if' statement, and are destroyed at the end of the statement. If you know you want to use the variable outside the 'if' statement, make sure your declare it before the 'if' statement.
