text: **11.5 Customized functions (Multiplatforms and z/OS only)**
  
  The user exits provide customized ways to perform tasks in Content Manager OnDemand. 
  You can use a user exit to customize logins, retrieve data from external locations, or send a 
  notification when a document is loaded. Programming of the user exits is an IBM Lab 
  Services offering; for more information, contact IBM Lab Services. 
  
  You can also use the sample exit source code to write your own exits. In this section, we 
  describe each sample exit that is provided in the*standard*Content Manager OnDemand 
  installation. 
  
  The sample source code for the Content Manager OnDemand user exits is provided for all of 
  the platforms. They are placed in the directories or libraries of Content Manager OnDemand 
  that are listed in Table 11-1. These sample user exit modules provide a skeleton for you to 
  program the exits.
