Table pub.mgd.mrk_current
Defines relationship between a Marker and its Current Symbol(s). A Marker may have one or more current symbols associated with it. Usually there is only one current symbol for a marker. But, if a marker is split, then each of the new symbols will be assigned as a current symbol of the split symbol.
