Original Message (ID '231523') By Michael:
In Response To 'Re: Checking dynamically updated variable' --------- Could you clarify with an example? In my view, variables are not dynamic per se, only output expressions are dynamic. Such expressions can update (change) a variable, such as an InputField, SetterBar, etc. Or they can change their output when a tracked variable changes its value. You can probably do what you want with compiled functions. For example: f = Compile[{{x}}, x^2,]; Dynamic[f[x]] Slider[Dynamic[x], {0, 4}]
