**Do not use leading zeros for any numbers!**

Any number with a leading zero will be treated as an octal number, so for example ``ALIAS(MY_ALIAS, 010)`` will assign the value of ``8`` to MY_ALIAS, not ``10``. This is a common mistake that can lead to very confusing behavior if you don't know about it. Always use numbers without leading zeros, for example ``ALIAS(MY_ALIAS, 10)`` to assign the value of 10 to MY_ALIAS.
