well I would like to add that you need to make sure that you always always need to have enough real free memory to support the IOs your system needs to do. If you dont, your system will stop ALL work and starts scanning and freeing up memory pages until there is sufficient free memory available and than restarts processing. If you are very low in free memory and your system had to do this frequently on a box with lots of IO, like a DB box, this is much worse for your performance than if you would run from paging space and it can grind a busy box to a complete halt - a fact that IBM support to this day prefers to completely ignore.

DwtListBoxSetPos(3Dwt)													    DwtListBoxSetPos(3Dwt)

Name
       DwtListBoxSetPos  -  Makes a specified position (item number in the list) the top visible position in a list box, or as close to the top as
       possible.

Syntax
       void DwtListBoxSetPos(widget, position)
	    Widget widget;
	    int position;

Arguments
       widget	 Specifies the ID of the list box widget whose specified item number in the list you want displayed in the top position.

       position  Specifies the item number in the list displayed in the top position in the list box.

Description
       The DwtListBoxSetPos function makes the specified position (the item number in the list) the top visible position in a list box.  The func-
       tion  determines  which	item in the list box is displayed at the top of the list box, the choice of which is limited by the DwtNitemsCount
       and DwtNvisibleItemsCount attributes to the list box widget.  When DwtNvisibleItemsCount is greater than 1 and  less  than  DwtNitemsCount,
       the list box widget fills the list box with the maximum visible items regardless of the position value.

       For  example,  if  DwtNitemsCount  is  10  and  DwtNvisibleItemsCount is 5, you cannot make item 8 be displayed at the top of the list box.
       Instead, items 6 through 10 would be displayed.	Setting position to 4 would make items 4 through 8 be displayed.  If DwtNvisibleItemsCount
       is 1, you can make any item in the list be displayed at the top of the list box.
