+====== NovoMotion Trigger Generator ======
+The NovoMotion deployment package includes a process to enable and disable triggers. This process is executed in the U2 environment and is called NOVO.E.T
-====== **NovoMotion Trigger Generator** ======
+Its sequence is as follows:
-The NovoMotion deployment package includes a process to enable and disable triggers.  This process is executed in the U2 environment and is called NOVO.E.T
+NOVO.E.T filename or ALL;   UPDATE or DELETE; and  ENABLE or DISABLE
-Its syntax is:
+  * **Filename** is the file to be acted upon. Using **ALL** instead of a specific file name will enable/disable triggers on all filenames.
-NOVO.E.T filename UPDATE/DELETE ENABLE/DISABLE
+  * Either **UPDATE** or **DELETE** can be specified - both can be specified if needed.
+  * Either **ENABLE** or **DISABLE** can be executed.
-  * Filename is the file to be acted upon.
+**Example:** NOVO.E.T IM UPDATE DELETE ENABLE
-  * Either UPDATE or DELETE can be specified - both can be specified if needed
+**Please Note:** Versions of NovoMotion before 4.0 allow the additional keyword AFTER to be used to change the execution order of the existing trigger in conjunction with the new NovoMotion trigger. At release 4.0 and beyond, the AFTER keyword is the default syntax and is no longer allowed.
-Example: NOVO.E.T IM UPDATE DELETE ENABLE
+If the **AFTER** keyword is used or if the NovoMotion version is 4.0 or greater, the order is as follows:
-  * Either ENABLE or DISABLE can be executed
+  - Request the write of data to a file
+  - Execute the Manage 2000 trigger
+  - Execute the NovoMotion trigger
+  - Write the base file record to disk.
-  * The additional keyword AFTER can be used to change the execution order of the existing trigger in conjunction with the new NovoMotion trigger. The default ENABLE command will execute the NovoMotion trigger and then check for the existence of a Manage 2000 trigger.   Specifically the order of events are
+THIS IS USEFUL IF THE MANAGE 2000 TRIGGER IS CHANGING DATA ON THE BASE FILE THAT SHOULD BE RESPECTED BY THE NOVOMOTION TRIGGER.
-  - request the write of data to a file
+Prior to NovoMotion version 4.0 and with no AFTER keyword, the order is as follows:
-  - execute the NovoMotion trigger
-  - execute the Manage 2000 trigger
-  - write the base file record to disk.
+  - Request the write of data to a file
+  - Execute the NovoMotion trigger
+  - Execute the Manage 2000 trigger
+  - Write the base file record to disk.
-If the AFTER keyword is used the order of the triggers is reversed.  The order then becomes
-  - request the write of data to a file
-  - execute the Manage 2000 trigger
-  - execute the NovoMotion trigger
-  - write the base file record to disk.
-THIS IS USEFUL IF THE MANAGE 2000 TRIGGER IS CHANGING DATA ON THE BASE FILE THAT SHOULD BE RESPECTED BY THE NOVOMOTION TRIGGER.
 Here is an example where the update trigger was enabled on the PT file:

-If the user DOES enable the NovoMotion trigger and an existing trigger is there, the NovoMotion trigger will execute the existing trigger code after it executes itself.   If the user's previous trigger is changing pertinent information in the file, it may be useful to execute the NovoMotion trigger after the existing trigger.  In that case the AFTER keyword is used to allow the existing trigger to call the NovoMotion trigger.
