Remove the single quotes around 'month'.

The documentation for %SYSFUNC, at <http://support.sas.com/onlinedoc/913/getDoc/en/mcrolref.hlp/z3514sysfunc.htm>, is incorrect. It says that quotes around character arguments are not required (implying optional), when in fact they are not allowed.

Quotes can be used in the second argument because it's numeric, not character.
