Understanding remote procedure handles

The THIS-PROCEDURE system handle returns the current procedure handle value from within any executing block of an external procedure. The THIS-PROCEDURE handle created within a PAS for OpenEdge session for a remote procedure request is a remote procedure handle. Its REMOTE attribute is, therefore, set to TRUE. If the REMOTE attribute is FALSE, then the current procedure exists as the result of a local procedure call (that is, a procedure call initiated and executed within the current ABL session context).
