Mask Ocean

[Bamba Sylla]

Hello !
Thanks for your answers !
But when i do :
basemap o set gxout shaded'
'd var'
'basemap o 0'
it says : error reading opoly.asc file
And when i do :
basemap L 7 2 M
it only put in red the contours of the countries and
doesn't remove preicp in the ocean, i don't know why?
