+[Maintainability Index][anchor0]: Do not write functions that have a very low maintainability index. This makes the code hard to maintain.
+
+Bad code
+
+    Any procedure / trigger that has a maintainability index < 20  
+      
+    
+
+Good code
+
+    Any procedure / trigger that has a maintainability index >= 20\.
+    The Maintainability Index is computed as a function:
+        - Lines Of Code (inverse proportional)
+        - the Halstead Volume
+        - Cyclomatic Complexity (inverse proportional).

+
+Bad code
+
+    Any procedure / trigger that is > 100 lines of code  
+      
+    
+
+Good code
+
+    Any procedure / trigger that is <= 100 lines of code.
+    A full C/AL Statement counts as 1 line of code
