Glad there are only 4 of them! warning -- INDEXMiddleEarth.th [289] -- equate used to define new station (DF4.46@df) warning -- INDEXMiddleEarth.th [313] -- equate used to define new station (YG6.25@yk) warning -- INDEXMiddleEarth.th [321] -- equate used to define new station (YQ3.15@yq) warning -- INDEXMiddleEarth.th [517] -- equate used to define new station (dj27.4@dj) Bruce
