The following corrections have been supplied by the DTR Editor, who is based in the UK, and therefore form part of the UK vote. (1) Section 3 of the DTR misses a necessary edit to a constraint in Fortran that currently prohibits allocatable dummy arguments and function results. This is in contradiction to sections 2.2 and 2.3 of the DTR, which discuss such entities. Add the following edit in section 3 of the DTR. 5.1, R501-R506, 3rd constraint [48:1-2] Delete: "that is not a dummy argument or a function result" (2) The DTR fails to specify the semantics of deallocation of objects with allocatable components. This specification was part of the original (Fortran 95) requirement but was accidentally omitted when it was converted to a TR. Add a new paragraph to section 2.4 (after the existing second para): "Deallocation of a variable containing an ultimate allocatable array component automatically deallocates all such components of the variable that are currently allocated." Add the following edit in section 3 of the DTR. 6.3.3.1, new paragraph at end of section [83:18+] "When a variable of derived type is deallocated, any ultimate component that is a currently allocated allocatable array is deallocated (as if by a DEALLOCATE statement." United States The U.S. National Body votes to Approve with comments ISO/IEC DTR 15581,Information technology - Programmng languages - Enhanced Data Type Facilities in Fortran. See comments below. Technical comment 1. The DTR misses a necessary edit to a constraint that otherwise prohibits allocatable dummy arguments and function results. Such a prohibition would make much of the TR moot. Add the following edit in section 3 of the DTR. 5.1, R501-506, 3rd constraint [48:1-2] Delete: "that is not a dummy argument or a function result" Technical comment 2. The DTR fails to specify the semantics of deallocation of objects with allocatable components. This specification is claimed to have been in prior drafts, but was apparently accidentally omitted. Add a new paragraph to section 2.4 (after the existing second para): "Deallocation of a variable containing an ultimate allocatable array component automatically deallocates all such components of the variable that are currently allocated." Add the following edit in section 3 of the DTR. 6.3.3.1, new paragraph at end of section [83:18+] "When a variable of derived type is deallocated, any ultimate component that is a currently allocated allocatable array is deallocated (as if by a DEALLOCATE statement." {Prevent memory leaks from nested allocatable array components.} _____________________ end of SC22 N2687 ___________________________
