### Working with Variables

Define
Variables are created with the command CREATE VARIABLE. The chosen characterization N, T resp. C defines the type of the variable. That's important for later use.
You have to assign a value to a variable. Thereby the respective type of the variable has to be considered again. The value assigned to a variable is also known as the content of the variable. It is optional to assign a name to a variable, but this should be done for any later referencing.

Modify
With the command MODIFY VARIABLE you have the possibility to change name and content of a variable.
Changing the content of a variable has an effect on the geometry when rule 1: save constructional relations is active during the time the variable is used.
Delete
For the deletion of variables (DELETE VARIABLE) the same rules apply as for the deletion of other geometrical objects. Deleted are all objects which depend on the variable that is deleted. The same is valid for geometrical objects for the construction of which such variables have been used and constructional relations have been saved.
Inform
With the calculator (tool box in main menu)

you will have a quick overview of the variables used within a construction.
Detailed information is available under general info within the main menu. There the names as well as the current contents and calculation rules, if necessary, are displayed for all or some special variables.
