Transaction From an Intelligent Device

Figure 1-2 illustrates the path of a transaction from an intelligent device, communicating

with a SCREEN COBOL program that uses the IDS facility of the TCP, to a Pathway

server. For this example, consider again a clerk at an order entry office. Using a

workstation, the clerk must update customer information for account number 2345678.

1. The clerk displays the order screen, a data entry screen, on a workstation. To the

Pathway application, the terminal is defined as object TERM-1.

2. The clerk enters the account number in the appropriate field and requests an update

to customer information by pressing a function key.
