Note: You should not specify a reset-action template in an action template that uses manual mode. Manual mode is designed to stay at a specific screen. The next transaction received by the session will start at the last screen of the action template that used manual mode. This next transaction should use automatic mode and specify a reset-action template that brings the session back to the starting screen of the first action template (that specified manual mode).

Screen templates

Screens used by the host computer could be a series of commands entered at the system prompt coupled with the system’s response to those commands, or screens defined by applications on the host computer. You should define screen templates that issue the system commands to start the application (usually as part of the initial-action template), and then screen templates that make menu selections and enter or retrieve data from the screens displayed by the application. This guide uses an accounting application as an example.

Each screen contains fields. For the VT100 Gateway, a field is any place on the screen where data is entered or displayed. For example, the cursor location after a system prompt where you would type a command is considered a field. Also, within an application, the area on the screen where an account balance is displayed is also considered a field (the traditional definition of a field).

For a specific transaction, specific data is entered in certain fields, and data is read from other fields. A screen template identifies those fields on the screen that are used to process a transaction. Only the fields that are used in the transaction are included in the template. Figure 2-9 shows a sample screen.
