RUGATHER { ON | OFF }
specifies that all of the RUs of a chain are accumulated for a host SNA 3270 session
before processing the data and writing the result to the CRT screen. This eliminates
unnecessary terminal writes for host sessions with small RU sizes.

SECURITY attribute
specifies a security attribute for each user. The parameters correspond to the
security attributes of the NonStop Kernel operating system. The security attribute
applies to commands that can directly alter the EM3270 emulator system state.
These commands are:
ADD LOG1/LOG2 SET STOP
ALTER DELETE RUN STARTSWITCH
The security attributes are A, G, O, -, N, C, or U. Each has the same significance as
the corresponding NonStop Kernel attribute. Quotation marks are required. When
no security attribute is supplied, the default value of N is assumed.

SHIELD { ON | OFF }
specifies whether certain errors are shielded from applications. When SHIELD is set
to OFF, the Tandem application is allowed to see certain errors: error 191 is reported
to the Tandem application; errors 110, 171, 173, 230, and 231 are retried five times
before the task enters a fault state that causes the error to be reported to the Tandem
application. When ON, errors 110, 171, 173, 230, and 231 are retried indefinitely.
The default value is ON.
