You need a 5250 emulator on your workstation to start the order entry application.
To start the 5250 application:
The application starts and shows the first panel. This first screen
prompts for a customer number. You have a choice of keying in the
customer number directly or you can press command key F4 to display
a list of existing customers.
You have started a 5250 emulation session, invoked the order entry application and seen the customer selection screen and now you are ready to begin Exercise 1.2: Accessing the online help.
