PIX Studio uses variables to store the temporary values of various data types. Their names must be unique within a script. PIX supports a wide range of variables such as numbers, rows, tables, logical types, and others.

A variable is declared by a simple entry of its name in the field "Variable" of Out-properties. It will automatically be assigned the desired type. You can also create variables in the "Value" field of In-properties of the "Properties" window,

in the window for editing variable fields,

as well as in the main script window

Types of variables are defined by:
- the Out-properties type that you can view in the context prompt by pointing the mouse cursor to the desired field name;

- dynamic typing.
PIX selects itself the variable type according to the calculations made earlier.
Here is the example.
When declared, the variable "x" received the base type <System.Object>.

The string value of the variable "x" has been added In the "Value" field and PIX dynamically defined the new type of variable "x".
