Release 10.1A: OpenEdge Development:
Progress 4GL Reference

FIRST-BUFFER attribute

Returns the buffer handle of the first table that has a buffer object. The table may be either a temp-table or a connected database, in that order. If no temp-table or database buffers exist in the session, it returns the Unknown value (?).

Data type: WIDGET-HANDLE

Access: Readable

Applies to: SESSION system handle

There is no LAST-BUFFER attribute associated with the SESSION handle since the chain is one-directional.
