FMGC Question LLXING/INCR/NO

Hi,
I need help with something I dont understand.....

On the Airbus 320 FMGC, if you do a Lateral Revision from the FLT/Plan Pg [2R] you get the option of LLXING/INCR/NO

I looked it up in the FCOM 4.3.25 and it quotes...

'This prompt allows pilot to create the latitude/longitude crossing point.
The increment (incr) ranges from 1 to 20 degrees, and the number of
crossing points 1 to 99.'

What on earth is this function??? I dont understand what format to enter in the information..... I dont know what useful information it will display.... Does anyone use this function? Is it for long haul use only?

Sorry if the answer is very obvious, but could someone explain it so a fool like me can understand please.

Thanks
