Release 10.1A: OpenEdge Development:
Progress 4GL Reference

FIRST-OBJECT attribute

The object reference for the first class object instance in the list of all valid instances created in the current OpenEdge session. If there are no class object instances in the current session, this attribute returns the Unknown value (?).

Data type: Progress.Lang.Object

Access: Readable

Applies to: SESSION system handle

Once you get the first object reference in the list, you can use the NEXT-SIBLING data member in the Progress.Lang.Object class to get the next entry in the list of object references.
