How You Can Declare Dynamic Array Variables
To declare an array variable, specify any system class or user class for the objects associated with the variable. The syntax is:
name = array of class [with] default null]
The following code is an example:
emparray = array of Emp;
When you declare an array, it is empty. OpenROAD does not populate the array automatically. There are a variety of methods that you can use to add rows to an array. For more information, see "Working with Arrays, Table Fields, and Collections" in the Programming Guide.
