it is NOT POSSIBLE to compare the values of two tags with each other.
That is correct. But it is now an easy thing to implement. There are a few syntaxes we could use such as: maxspeed < get_tag(maxspeed:forward) maxspeed < ${maxspeed:forward} The attached patch implements the dollar notation. So the first part of your example could be written as: maxspeed:forward=* & maxspeed!=* { set maxspeed='${maxspeed:forward}' } maxspeed:forward=* & maxspeed:forward < ${maxspeed} { set maxspeed='${maxspeed:forward}' } Note there are no quotes around ${maxspeed}. It's not limited to numeric comparisons, you could have: name != $name_int Currently you can't just have one of these by itself, it has to have another test first. I'm pretty sure that can be fixed, but that's one for later. (built jar: http://files.mkgmap.org.uk/download/161/mkgmap.jar) ..Steve
