Dial_next
When several dial sets are active at the same time, this command can be used to cycle between them in a forward direction. For example, the Move_fragment command activates two dial sets, one for the rotations around the x, y, z axes, and one for the translations. Dial_next will select the next dial set on the stack. This command changes this assignment by one block of four, cycling through 4 dial boxes. For each box number, there must be an entry in the database .box[number] Default examples are included in dialbox.o, dialbox_a.o and in the startup.o files.
