1. A two-dimensional array object of int is generated (number of elements = n).
2. A one-dimensional array object of int is generated (number of elements = m).
3. The one-dimensional array generated in [2] is set in each element of the first
dimension of anArray.
GET-ARRAY-LENGTH method (object method)
Explanation
This method returns the number of elements of an array object.
Syntax
INVOKE
anObject "GET-ARRAY-LENGTH" RETURNING elmNum
Parameter and return value
• anObject
Specifies the array object from which the number of elements is obtained.
• elmNum (attribute: PIC S9(9) COMP-5)
Returns the number of elements of an array.
GET-ARRAY-ELEMENT method (object method)
Explanation
This method fetches an element from an array object.
Syntax
INVOKE
anObject "GET-ARRAY-ELEMENT" USING inx RETURNING elemValue
Parameter and return value
• anObject
Specifies the array object from which an element is to be fetched.
• inx (attribute: PIC S9(9) COMP-5)
Specifies the subscript of the element to be fetched. The subscript begins
from 0.
• elemValue (attribute: Array element type)
Returns the value of the array element fetched.
