Example 1 - Making services available to selected address spaces shows how a service provider can supply services to users in selected address spaces. (The example shows only one user, but the extra steps for adding users are pointed out.)

Example 2 - Making services available to all address spaces shows how a service provider can make services available to users in all address spaces.

Example 3 - Providing non-space switch services explains how a service provider can provide non-space switch services.

For each example, assume that the service provider has obtained common storage that the user can access through name/token callable services. The service provider could use the area pointed to by the token returned by name/token callable services to store the PC numbers corresponding to its services. It could also store some of the lists it needs to invoke PC/AUTH services, and the lists that must be available to different address spaces. Assume also that SERVBLK, shown in Table 1, describes the common storage area. All examples use the declared storage areas shown in Table 1.
