Although many people are not aware of this feature, HyperCard will
evaluate any expression (including a mathematical expression) typed
into the message box. Personally, I find this more congenial (especially
for complex calculations) than using a "push-button" calculator, since
you can edit the contents of the message box before you press Return
to evaluate the expression. Also, it has the advantage of being available
whenever the message box is showing, and you can copy the result either
manually or via a script.
