MainBar System Class Added; FrameExec and FrameSource Get New Attributes
A new system class is added in this release of OpenROAD. A MainBar is a stackfield that can be attached to the side (top, bottom, left, or right) of a frame through its MainBar-related attributes.
MainBar has no attributes or methods, but the following attributes are added to the FrameExec and FrameSource classes:
MainBarBottom
Data Type: array of MainBar
4GL Access: RW
Contains the set of MainBar items that are attached to the bottom of the frame's form.
MainBarLeft

MainBarTop
Data Type: array of MainBar
