Defining an Application Structure Using ADSA › Instructions › Optionally Execute the Application › Invoke the application

Invoke the application

CA ADS applications execute under the CA ADS runtime system. To invoke the Department application from DC/UCF, you can enter the task code for the runtime system, followed by the application task code.

For example, assume that ADS is the task code for the runtime system and XXXDEPT is the task code for the Department application. You can invoke the Department application as shown:

ads xxxdept
 ▲       ▲
 │       │
 │       Sample task code for
 │       the Department application
 │
Sample task code
for the runtime system
                                                                [Enter]

The DEPTMENU screen is the first screen displayed.

DIALOG:                                                  PAGE:   1 OF:   1
  DATE:  08/19/99                                        NEXT PAGE:
                     DEPARTMENT INFORMATION APPLICATION
                                 MAIN MENU

      ┌-   _ ADD        (PF4)      ADD A NEW DEPARTMENT
      │    _ MOD        (PF5)      MODIFY A DEPARTMENT
      │    _ DEL        (PF6)      DELETE A DEPARTMENT
      └-   _ EXIT       (PF9)      TERMINATE APPLICATION

Alternatively, you can enable developers and users to simultaneously invoke the runtime system with an application. To do this, you associate the application task code with the runtime system in either of the following ways:

• At system runtime you issue a DCMT VARY DYNAMIC TASK command while using DC/UCF to dynamically associate a task code with the runtime system. Use of the DCMT VARY DYNAMIC TASK command is shown in Instructions For Executing the Application, later in this manual.
• At system-generation time you use the TASK statement in the system definition to associate the application task code with the CA ADS runtime system.

  This procedure typically is used for a production application. For more information, see CA IDMS System Generation Guide

After you invoke the Department application from DC/UCF, you can test out features that you've already implemented, as described below.
