|<iFirstColumn>||The number of the column that is to be shown as the first visible column. The column number refers to the list of the opened columns (see also bBrowser:ColumnOpenList).|
|<iOffset>||The offset of the first visible column related to the left margin of the dynamic data area. The offset can be less or equal 0. If the offset is 0, then the first visible column starts directly on the left margin of the dynamic data area. If the offset is less than 0, then the column is partly concealed by the left margin of the dynamic data area. As a default, the value 0 is used.|
|lSuccess||A logical value that indicates whether the column was set as the first visible column.|
|TRUE||The column was set.|
|FALSE||The column could not be set.|
bBrowser:SetFirstColumn() determines the offset for the specified and last visible column, and shows all the visible columns lying between them.
