Variables in Knowledge Builder have two primary uses:

Used as a simple global String or Numeric Variable type (when Array Size are set to 1x1) to store data processed by scripting procedures (not Decision Trees or Rules). String & Numeric Variables differs from Text & Numeric Objects in the following ways:

Variables have no Properties or Events
String Variables have a 'Variable Length String' option for unspecified length or very large strings (over 65535 characters)
Option to use a Numeric Variable as an "Object Reference" for referencing COM Objects (not JavaScript Deployment)
Variables are not affected by the @Clear command
Values can be captured on Dialogs using the "Variable Editor" control
Note that a Variable can be converted to an Object using the "Change ... Base Class To" option

1 or 2 dimensional global Arrays (Numeric or String type) with Array Size of up to 1000 elements in each dimension
String Array elements have a specified length (maximum of 65535 characters)
Values can be captured on Dialogs using the "Variable Editor" control for each element (by setting the control's dim1 & dim2 properties)
Use the @InitArray command to clear or set the whole array
