This Natural profile parameter defines whether the Natural input and output (I/O) remains unchanged (that is, terminal emulation in case of SPoD, and emulation from where Natural is started when calling Natural directly on OpenVMS) or whether the Natural Web I/O Interface is used.

Possible settings	ON	I/O via Natural Web I/O Interface.
	OFF	I/O remains unchanged (terminal emulation).
Default setting	OFF
Dynamic specification	yes
Specification within session	no

Notes:

1. The Natural Web I/O Interface displays the input and output data in a web browser. On platforms other than Windows, the Natural Web I/O Interface can only be used to display and enter U format fields with characters which are not contained in the current code page.
2. The parameter WEBIO can only be used when Natural is running as a server, not in an interactive Natural session.
3. The parameter WEBIO is not compatible with the parameter BATCHMODE. If the parameter BATCHMODE is set, WEBIO=OFF is assumed.
4. See also Profile Parameters in the Unicode and Code Page Support documentation.
