Application cell functions
If the caller hangs up before the transaction is completed, the COMA cell in
the clean-up branch of the START cell clears the memory and buffers
associated with the application.
Step Description
Cell 1 The ANSW cell answers the incoming call.
Cell 2 The GDAT cell plays a prompt requesting the caller to
enter an account number. The number entered is
stored in the ACCOUNTNUMBER buffer.
Cell 3 The MENU cell plays a prompt instructing the caller to
press 1 to get an account balance, or press 2 to get an
account update.
Cell 4 When the caller presses “1” on the telephone, the COMI
cell starts the transaction.
According to the COMI cell parameters in Figure 4-3,
the action template specified in the COMI cell
parameter window is “getbalance”. (This template is
used in the sample transaction described in Chapter 3:
Getting started, specifically Figure 3-11 on page 3-18.)
The COMI cell provides the contents of the
ACCOUNTNUMBER buffer to the host computer
application.
Cell 5 According to the COMO cell parameters in Figure 4-4
on page 4-7, the COMO cell receives the customer’s
balance from the BALANCE buffer.
Cell 6 The contents of the BALANCE buffer is played to the
user.
Cell 7-9 When the caller presses “2” on the telephone, an
account update is given because the application
communicates in a similar manner.
Cell 10 The caller hangs up and the application ends.
