# SENDER - Screen Output Destination for Asynchronous Processing

This Natural profile parameter specifies the destination where output from an asynchronous application is to be displayed.

Possible settings | 1 to 8 characters | Output destination, for example, printer.
Default setting | none |
Dynamic specification | yes |
Specification within session | no |

Notes:

1. This Natural profile parameter only applies to Natural under CICS, Com-plete, and IMS TM.
2. The destination specified applies to hardcopy output and primary reports.
3. Any additional reports are sent to the destinations specified with the `DEFINE PRINTER` statement (just as in a synchronous online session).

#### Platform-specific Characteristics

The following platform-specific characteristics apply:

Platform: | Comment:
--- | ---
CICS | The profile parameter `SENDER` specifies the CICS transient data (TD) destination and the terminal or printer for terminal output from asynchronous sessions. If the specified destination does not exist, the session output is sent to the specified terminal or printer. If the specified terminal or printer does not exist either, the session terminates abnormally. The default terminal output format for asynchronous sessions is a 3270 data stream. If the `SENDER` terminal specification is not a 3270 device, the Natural application must switch to the correct terminal type before the first output statement (for example, by specifying `SET CONTROL 'T=PRNT'` for a printer or by starting with profile parameter `TTYPE``=PRNT`). If you are routing all output to a (spool) destination, such as CSSL, the Natural application must be switched to line mode, for example, by specifying `SET CONTROL 'T=xxxx'` or by starting with profile parameter `TTYPE=xxxx`, where `xxxx` is `BTCH` or `ASYL`. In this case, two other profile parameters are relevant: `EJ` and `INTENS`. If you set `EJ=ON`, all lines are routed with a leading ASA control character. With `EJ=OFF`, there is no leading ASA control character. `INTENS` should be set to `1`, particularly if you have set `EJ=OFF`. Note For further CICS-specific functionality, see Asynchronous Natural Processing under CICS in the TP Monitor Interfaces documentation.
Com-plete | See Asynchronous Natural Processing under Com-plete/SMARTS.
IMS TM | The profile parameter `SENDER` specifies the default `LTERM`. This `LTERM` is always used when no other printer has been specified. You should always dynamically define a `SENDER` parameter in the `NIIBOOT` module. This is important when Natural tries to output error messages when starting a session: if no `SENDER` parameter is specified, there is no valid `LTERM` and `NATIMS` terminates the session.
