DO Values with Arrays of Objects

Imagine that we have already defined an object type EMPLOYEE which contains a member of type STRING. We create an array of EMPLOYEE objects and set the Name member of each of each object.

!MyEmployees[1] = object EMPLOYEE()

!MyEmployees[2] = object EMPLOYEE()

!MyEmployees[3] = object EMPLOYEE()

!MyEmployees[1].Name = ‘James’

!MyEmployees[2].Name = ‘Joe’

!MyEmployees[3].Name = ‘Mike’

We then wish to create a new array containing just the employees’ names.

!Names = ARRAY()

do !Person VALUES !MyEmployees

 !Names.Append(!Person.Name)

enddo

Each time round the do-loop, the do-variable becomes an object of the appropriate type, even if the array is a heterogeneous mixture of objects.
