For 'a+', that book, and perhaps the standard, does not specify where an *initial* read starts. It only says file position is set to end-of-file 'before each write' and that reads after a write (and vice versa) 'must' follow an intervening file-positioning call (fflush, fseek, fsetpos, rewind). > guess the GNU C library "innovated" on this point. If there is a hole in the standard, 'innovation' is required. Terry J. Reedy -- http://mail.python.org/mailman/listinfo/python-list
