Different transactions may access different fields on a screen. For example, a transaction to locate the payment due would only need to access that field, while a transaction retrieving the customer’s balance would only need to access the Current Balance field.

A screen template is an ASCII file created with a text editor. The screen template files you create must reside in or under the Meridian IVR 2.0/I /u/ivr/3270 directory and must have the file name extension .scn. For example, if you created a screen template called customer.scn, it would have these paths:

u/ivr/3270/customer.scn

For each accessed field, there should be a field descriptor specified that governs how data is retrieved from or entered in the field. The screen template can include both data input entries as well as data output entries.

Screen template syntax

The syntax of a screen template is shown in Figure 2-11.
