Preference File Structure
Preference files always begins with the *Id() statement followed by statements grouped in blocks.
Each block begins with a *Begin statement, such as *BeginDefaults(), *BeginPlotDefaults(), or *BeginDefinitions(), and ends with a corresponding *End statement, such as *EndDefaults().
- *BeginDefaults()
 - *BeginDefinitions()
 - *BeginStatsTemplates()
 - *BeginPlotMacros()
 - *BeginTemplexFunctions()
 
The *BeginDefaults() block is unique to a preference file while the *BeginDefintions(), *BeginStatsTemplates(), *BeginPlotMacros(), and *BeginTemplexFunctions() blocks are the same as those found in session files.
