[gembud] filling in continents in gempak

I am trying to create gempak maps in which I can fill in the continents.
Based on the script I have attached do you know what I can do to fill in
the continents?

I have tried created a *.gem file from the file world_topo.5min and use
that to fill in the continents but I have to create a new *.gem file
everytime I want to make a new map and when you have a program that is
generating a large amount of these maps it can cause some problems at
times.  Is there an easier way to make the maps with continental fills
based on the file I have attached?

Thank you for your help.
