--- Comment #4 from Ellis N. Thomas <ExtraLeveLInSoftware at ntlworld dot com> --- The decision to close this without any action seems unjustified. The problem is being rejected on the basis that the handling of the exception is faulty in the older Darwin. However, the fundamental problem is that this exception should not have been raised by OPEN (as in the cited sections of the Ada RM). Some fix to the relevant IO software is needed. The reply also states that what worked for I/O on VMS decades ago is essentially irrelevant - but regardless of whether OPEN is going to support another file being opened to Standard Input, if it doesn't it must say so by raising Name_Error or Use_Error as appropriate. In fact from the software developer's point of view it is clearly an advantage to be able to support interactive tools (like interpreters) written in Ada, and the ability to manipulate Standard Input is part of this. However, this facility itself is not the issue here. ENT/15-Aug-2013
