The following table summarizes the settings of the PROXY, REMOTE, and PERSISTENT procedure handle attributes for various types of local and remote procedure call scenarios.

In the previous table, caller handle refers to the handle returned by the RUN statement. This column is relevant only for persistent, single-run, or singleton procedures, because you can only reference the procedure handle of a procedure that you call with a RUN statement that includes the SET option. Callee handle refers to the procedure handle within the procedure that is being executed. You can use the THIS-PROCEDURE system handle to reference this handle, regardless of how the current procedure was called.
