WD2-GET-SESSION-VALUE

The WD2-GET-SESSION-VALUE function retrieves the value of a session field.

The function can be used also to retrieve screen dimensions since at the display of the initial window the following session values are set by Web Direct 2.0:

•	iscobol.wd2.on_client_info.desktop.width

•	iscobol.wd2.on_client_info.desktop.height

•	iscobol.wd2.on_client_info.screen.width

•	iscobol.wd2.on_client_info.screen.height

Dimensions are expressed in pixel.

Note - Screen dimensions are available after the display of the first window. They could be not available soon after the display as they depend by an event that the ZK Framework generates in response to the creation of a window. It's good practice to wait few seconds before inquiring screen dimensions.
