To: J3 07-247 From: Jim Xia Subject: Interpretation: Procedure characteristics and unlimited polymorphic Date: 2007 July 11 NUMBER: F03/0092 TITLE: Procedure characteristics and unlimited polymorphic KEYWORDS: Procedure, unlimited polymorphic DEFECT TYPE: Error STATUS: Erratum QUESTION: Consider abstract interface function foo (x) class(*) x class(*), pointer :: foo end function end interface procedure (foo), pointer :: proc_ptr procedure (foo) proc_tgt proc_ptr => proc_tgt According to the rules of procedure pointer assignment at [144:39-41], proc_ptr and proc_tgt are required to have the same interface characteristics. However because an unlimited polymorphic entity is not considered to have a declared type, the rules for characteristics of dummy data objects [256:26-32] and characteristics of function results [257:2-8] are not applicable. In addition, rules at [145:5-6] require that proc_ptr and proc_tgt have the same function return type. This also does not apply to unlimited polymorphic data. Is the example intended to be standard-conforming? ANSWER: Yes, the example was intended to be standard-conforming. An edit is provided to clarify this. EDITS to 04-007: [145:5] After "the same type" insert " or both unlimited polymorphic" [256:29] After "polymorphic," insert "whether it is unlimited polymorphic," [257:2-3]After "polymorphic," insert "whether it is unlimited polymorphic," SUBMITTED BY: Jim Xia HISTORY: m181 Submitted
