Yea. Sometimes our equations get real long. One way to make them shorter (per equation box) is to split the equation into part and then use custom pilot functions to write some of the parts.

There is a video which provides an introduction to pilot functions. You can watch it here. The idea is rather simple. Suppose you wanted to type the following equation into an input script:

(x^2 + y^2)*h*v/sin(sqrt(x^2+y^2))

One way to split this up is to define the function pf1 [on the “Functions screen”]. In the pf1 box type:

x^2 + y^2

Then, in the input script box, instead of typing the first equation above, you can write

pf1*h*v/sin(sqrt(pf1))

This is a little shorter. Perhaps you can use the same idea to shorten the equations you need to type in.
