Use Default Size Units BookFormat preference to set the units (inches, cm or points) used for new Scripts. This setting can always be overridden later using the property Size : Units.
Use Year to determine the value that should be assigned by default to new Scripts' "Year" property :
•The first option tells Q++ to use a given year for all new Scripts, until this particular value is modified.
•The second option tells Q++ to start using a new default year beginning on a given month. For example if you start typesetting diaries for the year N+2 in July of year N, you would set this option to July.
