After the create statement is placed in an SDL file, the OpenRender model specified by the create statement can be used just like an Alias model.
create shader ( model = new_shader, filename = "new_shader.o" );
.

shader grey (
model = new_shader,
lcolor = (150, 150, 150),
ldiffuse = 0.8,
glow = (20, 20, 180)
);
