According to the "official" source, the syntax was to be backported to Python 2.6: https://www.python.org/dev/peps/pep-3127/ The changelist of Python 2.6 seems to agree: https://docs.python.org/2/whatsnew/2.6.html#pep-3127-integer-literal-support-and-syntax > Anyway, using symbolic constants is certainly even better. Throughout the code, yes, but even those could be defined in terms of octal literals. :-) Best regards Markus Schaber CODESYS® a trademark of 3S-Smart Software Solutions GmbH Inspiring Automation Solutions 3S-Smart Software Solutions GmbH Dipl.-Inf.
