Define variables

You define all variables in the same way whether you are defining variables for a calc section or for a document. After you have created a variable and assigned a value to the variable, you can use it throughout your calculations in the same calc section or document. To create variables, see the following instructions.

Note:

The following only applies to Tedds for Word.

Variables can be equal to:

A value

For example x = 45 or Z = 245 N/mm²
A string

For example text = "This is a string of text."
The result of an expression

For example C = A + B

Variable naming rules

Variable names must follow some simple rules. They must:

Only contain alphanumeric characters (A-Z, a-z, 0-9), Greek characters, underscores (_), and full stops (.).
Note:
- Variable names are case-sensitive.
  For example, Area and area are two separate variables.
- Variable names take subscripts into account.
  For example, Aeff and A_eff are two separate variables.
Not be longer than 32 characters.
Not start with a number.
Not be the same as a Tedds function name (for example sin or median).
Not contain superscript characters.
Not contain any formatting other than subscripts.

Note: When a part of a variable name is in subscript, the part can contain spaces and a list separator (, or ;).

Assign a value to a variable

Type the variable name and an equal sign.
After the equal sign, type the desired value, expression, or string.

For example:

a = 45
Calculate the expression.

The variable is now stored in the variable list, and you can use it in later calculations.

Assign a unit to a variable

After the variable value, place a space. Then, type the desired unit.

For example:

a = 45 m
Calculate the expression.

The variable is now stored in the variable list with its unit, and you can use it in later calculations.
