Described are various methods and apparatuses for automatic updating of variables in a data language. A dynamic variable is updated by parsing an instruction written in the data language containing the dynamic variable, creating the dynamic variable in memory, assigning a value for the dynamic variable, and updating the dynamic variable value without parsing the instruction written in the data language containing the dynamic variable. The dynamic variable may also be updated by creating an object associated with the dynamic value, wherein the object determines the value of the dynamic variable. Further, an observing a function value may be associated with the dynamic variable and then a notification is given to the object when the function value has changed.
