Doug, Beta version 6.4.7.2 of the LDM definitely has a problem with PIPE actions (Gilbert Sebenste reported such to <address@hidden>. I've fixed what I think is the problem and made a new version. It's at ftp://ftp.unidata.ucar.edu/pub/ldm/beta/ldm-6.4.7.3.tar.Z Gilbert will, undoubtably, try it and let me know if the fix works.
