In some calculation functions, the calculated points are automatically stored in the active coordinate list (e.g. the polar survey). If none of the coordinate lists are selected as active, the program itself will not store the point, but you can store it manually by dragging it to any coordinate list. This can be convenient, for example, during testing calculations, where there is no need to store the results.
In the calculation functions, where it is necessary to enter the output file for the calculated coordinates (batch polar survey etc.), the output is automatically set as the active coordinate list at the launch of the calculation (unless you have previously chosen a different file).
