MODEL 204 HAS TERMINATED EXECUTION
IBM 3270 terminals (IODEV = 11)
This section summarizes the information needed to use IBM 3270s (and
compatible terminals) operating under TSO in full-screen mode.
Input lines
TSO users can utilize the full-screen input features described in “Full-screen
formatting” on page 9. These features allow the entire screen to be formatted
and displayed as a single entity. The user usually responds to prompts that are
displayed on the screen. When the entire screen has been filled in, the user
presses the Enter key, and the data is transmitted from the terminal to
Model 204 for processing.
Program Function (PF) keys are supported by Model 204 only when the user
accesses a screen formatted through the User Language full-screen formatting
feature. Otherwise, PF keys are not supported and cannot be used to enter
data. Any line entered by means of a PF key is considered null, and any data
entered is lost.
Attention key
The PA1 key serves as the attention key on IBM 3270 terminals, unless the
attention key has been reassigned by the user through the FATTN parameter.
For more information on the FSATTN parameter, refer to the Model 204
Parameter and Command Reference Manual.
Screen-formatting parameters
The screen-formatting parameters listed in Table 5-3 apply to IBM 3270
terminals being used through TSO. The PGSEP parameter is not listed; it is not
used with IBM 3270 terminals.
