Help for markers management (pins) on igo8

i would like to decide the color of markers putted on map when i use the instruction map.putpin. Instead currently the program uses cyclically the colors in pins.bmp and pins.spr. Somebody know how to proceed?

or any other system is acceptable to put symbols similar to the pins in the map, knowing the coordinates.

the important is the possibility to choose each time the symbol to be entered on the map

thanks
