Abstract

The 3270 terminal is widely used to link computer users with on-line information systems across a wide variety of communication links. The bottom line of the 3270 screen is called an Operator Information Area or OIA. The OIA contains information in terse symbolic form that indicates the state of the communication link, the keyboard mode and the condition of terminal subsystems. The information that is displayed in the OIA is cryptic and abbreviated. Without additional room to display a text message, the terminal operator may not understand the meaning of the OIA information to take the appropriate action. Additional room on the screen cannot be used without hiding other areas of the terminal screen containing the user's data or interrupting the operation of the terminal.

Diagnostic Information Area for a 3270 Terminal Emulator

       The 3270 terminal is widely used to link computer users
with on-line information systems across a wide variety of
communication links.  The bottom line of the 3270 screen is called an
Operator Information Area or OIA.  The OIA contains information in
terse symbolic form that indicates the state of the communication
link, the keyboard mode and the condition of terminal subsystems.
The information that is displayed in the OIA is cryptic and
abbreviated.  Without additional room to display a text message, the
terminal operator may not understand the meaning of the OIA
information to take the appropriate action.  Additional room on the
screen cannot be used without hiding other areas of the terminal
screen containing the user's data or interrupting the operation of
the terminal.

      Most 3270 terminal hardware has been replaced by programmable
workstations running 3270 emulation programs.  The programmable
workstation, with its larger available memory, larger screen size,
and program flexibility, gives the 3270 emulators additional
capabilities over the older non-programmable hardware.  This
environment can be used to enhance the performance and functionality
of the 3270 terminal.

      The only area on the 3270 terminal that is available for use
without disrupting the operators use of the terminal is the area in
use by the OIA.  The OIA, as currently structured, does not allow for
the display of text informational messages to the operator.  The OIA
must also be retained for the information that it provides.
