Subject: [SWIPL] compare coordinates

Hello!

I have one questions. Is there a possibility to know if there are two
coordinates NOT the same? i have two values X and Y, and want to know if
they are not the same. With compare i can only determine if the are the
=,>,<, right? Can i use NOT in some way?

Thanks for answers

sebastian
