J3/11-196 To: J3 From: Malcolm Cohen Subject: ENTRY interp Date: 2011 June 13 ---------------------------------------------------------------------- NUMBER: TITLE: ENTRY point RESULT variable KEYWORDS: ENTRY, RESULT DEFECT TYPE: Erratum STATUS: J3 consideration in progress QUESTION: MODULE m REAL x CONTAINS FUNCTION f() f = 1 x = 2 RETURN ENTRY e() RESULT(x) x = 3 END FUNCTION END MODULE Is this standard-conforming? If so, what is the result of referencing f() and e(), and what effect does that have on the module variable x? Note that the standard prohibits dummy arguments of an entry point from appearing in executable statements ahead of the ENTRY statement (unless they are also dummy arguments of an earlier ENTRY statement or the FUNCTION statement), but makes no similar requirement on the RESULT name. ANSWER: This program was not meant to be conforming. An edit is provided to correct this mistake in the standard. EDIT: Append new statement to 12.6.2.6p8 [310:20], "A name that appears as a in an ENTRY statement shall not appear in any executable statement that precedes the ENTRY statement." Append new statement to 12.6.2.6p9 [310:23] "A name that appears as a in an ENTRY statement shall not appear in the expression of a statement function unless the name is also a dummy argument of that statement function.
