ReadBooleanDef(ValueName: String; DefaultValue: Boolean): Boolean;
ValueName. Name of the parameter, which value must be obtained.
DefaultValue. Value that is used if parameter does not exist.
The ReadBooleanDef method reads logical value from the REG_DWORD parameter in the registry.
If the ValueName parameter does not exist, the method returns DefaultValue.

Sub UserProc;
Var
RegKey, SubKey: IRegistryKey;
b: Boolean;
Begin
RegKey := RegistryClass.CurrentUser;
SubKey := RegKey.OpenSubKey("Software\MyProject\Params", False);
b := SubKey.ReadBooleanDef("Param1", True);
End Sub UserProc;
After executing the example logical value is read from the parameter with the Param1 name located in the registry subkey [HKEY_CURRENT_USER\Software\MyProject\Params] into the "b" variable. If the parameter does not exist, the variable is set to True.
