--- Comment #16 from G. Steinmetz <gs...@t-online.de> --- Yeah, and other parts are sort of amazing too. Let me allow to cite the complete 4.2, item 2, points (1)-(10) : 2 A processor conforms to this document if: (1) it executes any standard-conforming program in a manner that fulfills the interpretations herein, subject to any limits that the processor may impose on the size and complexity of the program; (2) it contains the capability to detect and report the use within a submitted program unit of a form designated herein as obsolescent, insofar as such use can be detected by reference to the numbered syntax rules and constraints; (3) it contains the capability to detect and report the use within a submitted program unit of a form or relationship that is not permitted by the numbered syntax rules or constraints, including the deleted features described in Annex B; (4) it contains the capability to detect and report the use within a submitted program unit of an intrinsic type with a kind type parameter value not supported by the processor (7.4); (5) it contains the capability to detect and report the use within a submitted program unit of source form or characters not permitted by Clause 6; (6) it contains the capability to detect and report the use within a submitted program of name usage not consistent with the scope rules for names, labels, operators, and assignment symbols in Clause 19; (7) it contains the capability to detect and report the use within a submitted program unit of a non-standard intrinsic procedure (including one with the same name as a standard intrinsic procedure but with different requirements); (8) it contains the capability to detect and report the use within a submitted program unit of a non-standard intrinsic module; (9) it contains the capability to detect and report the use within a submitted program unit of a procedure from a standard intrinsic module, if the procedure is not defined by this document or the procedure has different requirements from those specified by this document; and (10) it contains the capability to detect and report the reason for rejecting a submitted program. Thanks !
