-            Method (_CRS, 0, NotSerialized)  // _CRS: Current Resource Settings
-            {

-                {
-                    WordBusNumber (ResourceProducer, MinFixed, MaxFixed, 
PosDecode,
[ ... ]

+            {
+                WordBusNumber (ResourceProducer, MinFixed, MaxFixed, PosDecode,
[ ... ]
