A variable of type Nothing is an undefined variable. When converted to a string with str or format, this variable will always return scalar bool array string 0xe0ffffef (in Armed Assault) or scalar bool array string 0xfcffffef (in Operation Flashpoint).
Undefining Variables
You can use nil to undefine variables.
myVar = 1; ... myVar = nil; myVar => undefined
Comparisons
No comparison with variables of this type will work.
Example:
// error if (undefinedVar == ...) then ...
// error if (undefinedVar == undefinedVar) then ...
