for(new i = 0; i<sizeof(Coords); i++)
{
      if(IsPlayerInRangeOfPoint(playerid, range, Coords[i][XXX], Coords[i][YYY], Coords[i][ZZZ]))
      {
            // so the if statement check if you are standing near these coords. 
            // here you can insert any action
            break;
      }
}

the question is how you want to check it?

Check when someone enter a command?
Check when someone gets close to these coords?
