    Dear friends,

    Thanks, as always, to all our cheerful friends at NCAR for their assistance.

    I think I followed Rick's instructions here correctly but (my particular
    problem- there might be others) is that even after his remedy, the file :

    /usr/local/ncarg/lib/ncarg/database/pwritdata

    was missing from its desired location.

    It seems that the make in
    > $NCARG/ncarg2d/src/db/pwritxnt

    did not copy the file to the desired location. A simple copy did and now my
    pwrit* calls seem to be working satisfactorily.

    However, some examples are missing their annotation which suggests to me that
    probably there is a similar problem with the fontcap make.

    I cannot see the answer immediately. Is someone able to help and perhaps see
    the wider implications of what has happened here?

    Yours sincerely,

    Bill
