text: **Activating the report specifications archive definition exit**
  The report specifications archive definition exit is implemented by a single DLL,**ARSUUPDT**. 
  **ARSUUPDT**is a DLL module that is written in the C programming language. The samples that 
  are shipped (**ARSUUPDT**and**ARSUUPDC**) initialize the**ARSUUPDA**structure and call the**ARSUUPDX**
  **ARS.RSADUPDT**exit driver. 
  
  The**ARSUUPDT**DLL invokes module**ARSUUPDX**. Module**ARSUUPDX**interfaces with the MVS 
  Dynamic Exit Facility to perform the following actions: 
  
  (cid:2) Define the logical exit point name: ARS.RSADUPDT 
  
  (cid:2) Route control to a set of exit routines that are associated with MVS and process the 
  results of their execution 
  
  Module**ARSUUPDZ**is implemented as dynamic exit routine that is associated with MVS. An exit 
  routine is eligible for execution after it becomes associated with the logical exit point. The 
  MVS Dynamic Exit Facility provides several methods for performing this association.
