When applied to a widget or object handle, this attribute always returns a handle. This handle is either valid or invalid based on the state of the instantiating procedure. The instantiating procedure for a dynamically created object might no longer be running. In this case, the handle is invalid.

Note: Since you can never be sure of the state of an instantiating procedure, never use this attribute as a chained attribute.

In general, INSTANTIATING-PROCEDURE returns the procedure handle for the procedure in which the DEFINE or CREATE statement is executed. Following are the exceptions:

Although this attribute applies to all widgets and handles, not all system handles are associated with an instantiating procedure and do not return a procedure handle. For these system handles, this attribute returns the Unknown value (?). The following system handles always return the Unknown value (?):

CLIPBOARD system handle
CODEBASE-LOCATOR system handle
COLOR-TABLE system handle
COMPILER system handle
DEBUGGER system handle
DSLOG-MANAGER system handle
ERROR-STATUS system handle
FILE-INFO system handle
FOCUS system handle
FONT-TABLE system handle
LAST-EVENT system handle
LOG-MANAGER system handle
RCODE-INFO system handle
SESSION system handle
WEB-CONTEXT system handle
