Substituting intermediate variables can sometimes simplify expressions calculated by the program. Try this option to see how it affects your output:
| 1. | Select  an output calculation. |
| 2. | Click the Use Intermediate Variables check box. |
| 3. | Click the box again to change back to the previous form. |
If Use Intermediate Variables is not checked, the Show Intermediate Variables is inactive.
Note: Intermediate variables are not always used in calculations, in which case this box will have no effect.
