FUNCTION MENU

## 1. Data comparison

Makes comparison between countries.

Select a data from the drop down list and Amiglobe will make the comparison. The `compare on map` button will paint the countries according to their rank in the list. Only numeric data can be compared.

## 2. Create compound data

Create user-defined data composed of two existing data.
The compound data will be the result of the left data with the right data and the operator (+, -, X, or /). When you begin with Amiglobe, there is already one compound data: population density, which is population/total area. For example, let's say we want to add the "balance trade" data, which is the exports minus the imports. When we are ready, we click on `Add` and we have to choose a group for this new data.
We choose economy, and place the balance trade just after the exports and imports data, with the down button. This will make this data appear there in the info window. We can check this by clicking on the button.
User-data are saved to disk. If you start Amiglobe directly from a CD-ROM, you cannot save these data to disk.
To remove an existing compound data, click on `Remove` in the Create compound data window

## 3. Set/Remove source/target point

You can set two special point in Amiglobe: the source point and the target point.

When the source point is set, Amiglobe will show the shortest path between the source point and the mouse pointer, or to the destination point, if set. The length of this path is shown in the status bar.

## 4. Show path

Toggle the draw of the shortest path between the source point and the mouse pointer/destination point.
