Communications/Transactions Guide and Reference
Use the 3270 Screen - Settings window to change the attributes of a 3270
Screen.
Use the General tab to work with the
following:
- Terminal id
- From the Terminal id 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.
- Settle time
- In the Settle time field, type the 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.
- Key sequence validation string
- In the Key sequence validation string field, type a character
string unique to the application panel you want to identify. VisualAge
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.
- Build records
- 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. 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.
- Dump to file
- 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.
Use the Input fields tab to work with the
following:
- Input fields
- Use the Input fields table to view the input field records for
the dataset. You must first select Build records from
General page to fill the table with the input field records. You can
update only the names of the fields in this table.
Use the Output fields tab to work with the
following:
- Output fields
- Use the Output fields table to view the output field records
for the dataset. You must first select Build records from
General page to fill the table with the output field records. You can
update only the names of the fields in this table.
