Informix Error -4066

-4066 RETURN statement not allowed in the body of intrinsic functions.

This statement is part of the definition of an intrinsic member function (the class constructor, !copy, and so on). These functions do not have explicit result values; or more precisely, code that the compiler automatically generates produces their returned values. Delete the RETURN statement.

Oninit® Troubleshooting Guidance

Reasons / Common Causes

-4066 fires when a RETURN statement appears inside an intrinsic member function's body (the constructor, !copy(), etc.) — per the official guidance, intrinsic functions don't have explicit result values; the compiler automatically generates the code that produces their returned values.

A RETURN statement inside an intrinsic member function, per the official guidance — the direct, only cause.

Solutions / Resolution

Delete the RETURN statement, per the official guidance.

Examples

A RETURN statement inside a constructor

CLASS Order
  FUNCTION Order()
    LET SELF.status = "New"
    RETURN
    -- -4066: RETURN is not allowed in an intrinsic function body
  END FUNCTION
END CLASS

Corrected

CLASS Order
  FUNCTION Order()
    LET SELF.status = "New"
  END FUNCTION
END CLASS

Diagnostic Checks

Check every intrinsic member function's body for a RETURN statement, and delete it.
