Define a MathCAD document as a function

Hi,

I have a Mathcad document that calculates a single value based on two input values. In between, there are a handful of constants defined, some preliminary calculations, 2 solve blocks and a couple of simple equations at the end. Its working great, but I need to do this calculation over and over again with different input values.

I know you can define a solve block as a function, but is it possible to define an entire document as a function? If not, is there a way to bunch up a load of equations and 2 solve blocks into a single function?

Many thanks!

Oliver
