Type a mapset name if you want to override the AMB-generated mapset name; maximum seven characters. To generate a multiple-map mapset that includes some or all screens, assign the same mapset name to the applicable screens in the application. The default mapset name reflects the number of characters in the screen name, as follows:
4-char name - screennameSET
5-,
6-char name - screenname$
7-char name - screenname$, where $ replaces the seventh character
