llRequestInventoryData() dataserver result not what i expected

I pass the name of a LandMark which is in inventory to llRequestInventoryData(). In the dataserver() event, I get back the correct request key, but the data string is not what I expect in a SIM-local vector; it is "<-26611.869141, 5567.740234, 21.600000>" the 21 is about right, the rest is not what I expect.

I have llOwnerSay() debugs all over the place to be sure I am really passing what I think I am passing. I can teleport to the LandMark by right click.

FWIW, my intent is to use it to call llMapDestination(), having previously extracted the target SIM's name from the LandMark's name.

Is this a landmark in a different region from the one you're currently in? Because the vector you get back from llRequestInventoryData is the landmark's position relative to the corner of your current region.

Thanks, but adding llGetRegionCorner() gets me a global-relative vector, while I need a vector relative to the corner of the target region in order to pass it to llMapDestination().

I am tempted to string parse the region-relative vector out of the LandMark's name, but that would rely on the name not being edited.

Hint: I am trying to script an object into which one dumps arbitrary landmarks and it allows you to teleport to one using llMapDestination().

Seems like llGetRegionCorner() would be useful here (though I've never tried to use the landmark data returned by the dataserver).
