The Before and After Code is called every time the Process or Template is called, regardless of the Command (or function) that the Process or Template is being called for.

Command is the first parameter passed into all Before and After Code.

It is up to the developer to write code to check what Command is being performed, and then to behave appropriately.

For example, it would be appropriate to derive data within Process Before Code when the Command was 'Save' or 'Load', but it may not be appropriate to derive data when the Command was 'Get'.

A complete list of Command values that can be passed, is contained with the Freedombase Help pages. However, the Command values that will be checked for/acted on the most often, are Save, Load, Delete, and Get.

It is also possible to pass custom Command values, and for the Before or After Code to check for and to behave differently depending on what Command value was received. This allows custom functions to be added into a Freedombase controlled system with ease.
