You can use icons and text to customize your map. Icons can consist of different pins, stars, flags etc.. 

This is done by the parameter:

icon_(x)

After defining the icon it is positioned on the map with a further parameter "obj_pos_(x)".

Unique use of an icon: 
It is also possible to make a unique position directly with the icon definition. But then it is no longer useful to use the parameter “obj_pos (x) ”.

obj_pos-Parameter

N (Name):
Name for icon!

3 Ways to define a position ion map:

LT:;LN:
Position with Latitude/Longitude values

A:
Define with Address

X:;Y:
Absolut position on map.
