From the Terminal drop-down list, specify the one-character character name of the emulator session you want to use for host interaction. The sessions currently available are listed.

This must be one of the emulator session names configured in the setup of your communications software.

In the Settle time field, type the number of seconds it takes a screenChanged event to gather multiple events. This is done to prevent multiple events from executing when the host updates the screen in several short blocks. Specify a nominal response time for the network. The default is one second.

In the Key sequence validation string field, type a character string unique to the application panel you want to identify. VA Smalltalk uses this string to detect the particular menu or panel you want the 3270 Screen part to interact with.

If the host application assigns a unique number or name to each screen, you can specify that name or number here. Otherwise, use any character string that appears only on the panel you want to identify.

The string you specify can be no longer than 132 characters long and cannot span lines.

Select Build records to capture the input field records and output field records, based on the contents of the current screen. These fields are then accessible through the inputFields and outputFields attributes of the 3270 Screen part.

After you have built these records, you can tear off individual records and place them on the free-form surface to use in building your application.

Select Dump to file to have the input field records and output field records labeled and stored in a dataset. The contents of the input field and output field records are also stored in the dataset.

You must select Build records to capture the contents of the current screen before you select Dump to file to place them in the dataset. If you do not select Build records first, when you select Dump to file an empty dataset is created.
