Tailoring a 3270 Screen part
To identify the host application panel represented by a 3270 Screen part, fill in the following fields in the 3270 Screen Settings view:
Terminal id
The single character name of the emulator session to use for host interaction. This must be one of the emulator session names configured in your Communications Manager setup.
Settle time
An integer representing the number of seconds it takes a screenChanged event to gather multiple events. This is done to prevent multiple events from running when the host updates the screen in several short blocks. The Settle time should be set to the nominal response time for the network. The default time is one second.
Key sequence validation string
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, specify it 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 and cannot span lines.
The Build records push button in the 3270 Screen Settings view causes VA Smalltalk to identify all of the input and output fields on the specified screen. These fields are then accessible through the inputFields and outputFields attributes of the 3270 Screen part.
Note:
In order for the Build records push button to function, the host screen specified in the 3270 Screen settings must be displayed in the specified emulator session.
After you build the records that represent the fields on the screen, you can customize the names of the fields by directly editing the field names in the second and third pages of the Settings view.
Note:
When you customize the name, you should not use the refreshFieldDefs action because it will set the field names back to the default field names. Any connections you might have to customized field names will no longer work.
If you want to generate a formatted report of the data captured by Build records, select the Dump to file push button. The Communications/Transactions feature will prompt you for a file name to contain the report.
