    Hello,
    There is a discussion regarding NCAR graphics going on in a
    local tech support group here at FSU MET. The "metlab" box
    is a Sun Microsystems "SunRay" setup ... one server(Solaris),
    and with twenty or so Xterminals (Sun Appliances). For some
    reason there is a problem when several different users on this
    system try to use NCAR graphics. Does anyone have ideas as to
    what may be causing this problem.
    Sincerely, Bob Broedel, Meteorology, Florida State University

    This is what I thought initially, and it still may be the case.
    However, in this case the compiler typically gives a licence error
    and doesn't allow you to compile (and then locks other users from
    compiling for some period of time). In our case, the program appears
    to compile fine, but the output from execution is incorrect.
    Clearly there is a problem with multiple users somewhere - may
    well be fortran and not ncarg.
