Wait for Data from the Application. CA CA TPX Session Management

CA TPX Session Management is a software product that allows users to manage and control their sessions within the TPX environment. It provides a comprehensive set of tools for users to create, store, start, and stop ACL/E programs, which are used to automate tasks and interact with applications. It offers features for interacting with applications, working with data on the screen, and defining and manipulating variables. The product also includes features for combining session information and managing errors.

Receive Data from the Application

Output from the application can continue to be displayed on the screen during the

"wait" period.

Wait for Data from the Application

You can also tell the program to wait for data from the application by including the following command:

WINP

You need to use this command only if output is going to come from the application before any action key statement (ENTER, CLEAR, PA, or PF) is executed.

You use the WINP statement primarily in startup ACL/E programs to ensure that these programs wait for the application's first screen or good morning message.

You can also use the WINP statement for applications that constantly generate output, such as CA-Remote and VM. In these cases, you may want to search the screen image each time the application sends data, and if it is not what you are looking for, use the

WINP command to receive the next application data.

Problems with the WINP Command

Two problems can occur with the WINP command.

■

If the application sends no data, the ACL/E program will go into an infinite wait.

■

If you use WINP to wait for data to be displayed and SEARCH to examine the data after it has been displayed, it is possible for the program to go into an endless loop.

For example, a program might have code similar to the following:

LOOP1 WINP WAIT FOR DATA FROM APPLICATION

SEARCH 'Ready' IS THE READY PROMPT DISPLAYED

BRANCH NE,LOOP1 NO, WAIT LONGER

If the string "Ready" is never sent from the application, the program will go into an endless loop waiting for it to be displayed. Even if the application sends data that the program does not use, the WINP command will tell the program to continue execution.

Unless you take measures to prevent an endless loop, the program can go into one if unexpected data is sent from the application.

Prevent an Infinite Wait

To prevent an infinite wait, specify a time-out period using the OPTION command with the TIME operand. For example, to tell the program to branch to the statement labeled

RESUME after 20 seconds of inactivity, use the following statement:

OPTION TIME=20,RESUME
