The buttons will be left-justified if DSB_BOTTOM is specified, or positioned towards the top if DSB_RIGHT is specified. (default)

Discussion
L_BUTTONSET defines the placement of a set of buttons for a list. Every button is contained within a set and only one button set is allowed per list; therefore, calling L_BUTTONSET will affect all buttons for the list.
The background rendition of the button area is defined by the background rendition of the input window at the time that L_CREATE is called.
This routine is ignored on Unix and OpenVMS.
