.NET Explorer supports complex data types such as arrays and objects as both input data and output data. The Output Value Wizard assists you in using such data as variables.
Storing Array or Object Output Data as Variable Explains that when a method returns an array or an object as output data, you can store the value in a variable of either
local or global scope.
Defining Array Elements Explains that when a method requires an array as an input parameter, you can define the number of array elements.
Defining a Column-Bound Variable Explains that in addition to standard random variables, random values bound to multi-column data files can also be defined.
