Are you following the on line directions? There's a set for the source distribution and the binary distribution accessible from http://www.unidata.ucar.edu/packages/ldm/index.html Once it's installed, you need to be user 'ldm' when you make the queue and run the ldm. Did you do that? Anne -- *************************************************** Anne Wilson UCAR Unidata Program address@hidden P.O.
