Property of the ScriptLine : BookFormat.
Use this property to set the reference year for the current Script. By reference year we mean a year that is used as reference for the calculation of Begin Rules/End Rules of DiaryGridLines. This does not mean that the DiaryGridLines of a script are limited to a single year.
For example, if you wanted to display the 12 months of the following year (ie. the year after the Year property), you would set the Begin Rules/End Rules as follows :
The value of the Year property is displayed in the Scripts Editor, on the BookFormat ScriptLine.
You can use the preferences to set a default rule or value for this property.
