Using variables allows you to use the results of previous calculations in later calculations. For further information on variables and variable levels, see the following paragraphs.
Note: The following only applies to Tedds for Word.
Variable definitions
All variable definitions take a similar form. The minimal variable definition must include:
In addition, most variable definitions include:
 An explanation
 A delimiter
 A unit
The components of a variable definition are very similar to the component of calculations. For more information on each component, see The components of calculations.
Variable levels
Tedds for Word recognizes three different levels of variables:

Calc section variables

Document variables

System variables
This is also the order in which Tedds for Word searches values for each variable that you place in your document. If Tedds for Word cannot find the value in one of the variable levels, a variable definition error occurs.
Note: You must define each variable before you recall it later in your calculation.
