Sharon,
First of all, you'll need to split your coordinates into 2 columns,
one for eastings, one for northings. You can then use the 'Create
Points' function to map these points. There is an option in the
dialog box to choose a different projection system. Pick the
'Projection..' button and you'll get another dialog. In this, select
'British Coordinate systems' from the 'Category' popdown list and
then select 'British National Grid' from the 'Category Members'
listbox. Select OK.
Back in the main dialog, you need to select the correct columns from
your database to provide the X and Y cooordinates, and by the looks
of your data, multiply the coordinates by 100 to give values in
metres.
You can also select a symbol style for your points.
And then pick OK!
You can then open the table in a mapper.
Hope this helps.
Regards,
Keith
