(like you are doing) because you have an alphanumerical index that can
reflect the content. It makes writing code easier.
In your example, you had to remember what 1,2,3 and 4 stands for. If you
use a struct this is easier
Example:
Employee = ArrayNew(1);
Employee[1] = "Pascal";
Employee[2] = "Peters";
Here you have to remember 1 stands for first name and 2 for last name
Employee = StructNew();
Employee["firstname"] = "Pascal";
Employee.lastname = "Peters";
It is easier to know what employee.firstname means (and makes more
readable code).
I only use arrays if I need ordered data (that's what they are for).
