Object Entries
The exact representation of an ADI depends on its number of elements. In the following exam-
ple, ADIs no. 0002h and 0004h only contain one element each, causing them to be represented
as simple variables rather than arrays. The other ADIs have more than 1 element (of the same
data type), causing them to be represented as arrays. If an ADI has more than 1 element, of dif-
ferent data types, it will be represented as a record.
