Predefined Processes
APPX provides a number of standard processes that you can invoke, or are automatically invoked, at appropriate points in your applications. For example, APPX contains a standard DISPOSITION input process that allows users to specify certain print-related information that controls how, when, and where a report is to print. This DISPOSITION process resides as a predefined process in the runtime application. To invoke this process as a child in an application, you identify the application ID as '---', the process type as INPUT, and the process name as DISPOSITION.
You cannot modify any of the predefined processes, although you can, for example, develop your own version of a DISPOSITION process by defining an input process in your own application. Then, instead of executing the DISPOSITION input process from the '---' application, you invoke the DISPOSITION input process from your own application. It is recommended that you define all these types of processes in a separate application so that they can be referenced easily for system-wide use.
The following is a list and brief description of the predefined processes that are available in APPX:
APPX MENU, which allows a user to run database and provides access to system administration, and application design.
BEGIN LIVE OPERATIONS, which transfers the run phase from initial setup or recovery processing to live operations.
CHECK GUI CLIENT, which determines if the current engine is connected to a GUI-enabled client.
DISPOSTION, which allows a user to provide information that controls how and where a report is to print.
ENTER BILLING CODE, which allows a user to enter a value into the predefined field BILLING CODE.
GET CMD LINE PARM, which checks for the existence of a parameter on the command line used to invoke the current engine.
GET ENV VAR, which retrieves the contents of an environment variable.
GET FILE FROM CLIENT, which retrieves a file from the client system and stores it on the server.
PROCESS QUERY RECORD, which potentially adds a PCF record to the result set of a query.
SELECT DATABASE, which allows a user to select the appropriate database.
SEND FILE TO CLIENT, which retrieves a file from the server and stores it on the client system.
See Predefined Fields and Processes for details on the predefined processes.
