--- Comment #4 from jvdelisle at gcc dot gnu dot org 2007-04-14 03:10 --- My interpretation of the standard as quoted in the original post. The value of POSITION can only be APPEND if we are positioned just before the EOF record or if there is no EOF record and the position is at it's terminating point. In the case given, there is an EOF record, so that rules that part out. The question then is after the first read, what is the position? The position after the first read is just before the EOF record. So the POSITION in this case should be APPEND. To fix this, we can have the INQUIRE statement attempt to read one more byte. If it is successful, we back up one byte and report ASIS. If we get an EOF trying to read the one more byte, the we report APPEND. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31532

--- Comment #2 from fxcoudert at gcc dot gnu dot org 2007-04-13 15:24 --- (In reply to comment #0) > If the file has been repositioned since the connection, the > scalar-default-char-variable is assigned a processor-dependent value, > which shall not be REWIND unless the file is positioned at its > initial point and shall not be APPEND unless the file is positioned > so that its endfile record is the next record or at its terminal > point if it has no endfile record. I'm not too skilled at reading normative language, but I guess it only says that if we're not at endfile, if can't be APPEND. It doesn't say that when we're at enfile, it shall be APPEND. Of course, there also is the quality of implementation issue to consider. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31532
