3. In the macro, we add two actions:

– An Add Prompt Action to request the account number needed for the

customer information request. The variable name is account. See

Figure 2-74.

– An Extract Prompt Action. The variable name is myresult. We use this

extract action to show the results of the request. See Figure 2-74.

2.3.2 Generating an Integration Object with a 3270 application

In the beginning of this chapter, we explain that you can generate Integration

Objects using APIs or macros. In this case, we use the macro to generate the IO.

1. As shown in Figure 2-75, select project name

→Macros →macro name

(TCHM2). Right-click and select Create Integration Object.

2. After a few seconds, HATS generates a Java application with the same name

of the macro. You can see the IO generated when you select project

name

→Source →IntegrationObject →TCHM2 as shown in Figure 2-76.

3. Example 2-5 shows the IO code that you can use to validate your IO.
