Double-click the mapset name in the tree view in the left-hand pane of the painter window to display the Mapset Properties dialog box, shown in the figure below.
These properties set the operand values for the corresponding BMS map definition macro DFHMSD.
Pages on the dialog box show the mapset properties. The Standard BMS page is displayed only if the painter is configured for standard or full BMS. DBCS attributes are displayed on the DBCS page but they cannot be changed
