   Using the vareas section of ps.map, is it possible to specify transparency
in the fcolor specification?

"fcolor none" should result in the areas be unfilled.

If you want "translucency", PostScript doesn't support that. However,
you can use the "pat" option to specify a pattern. Varying the pwidth
option should affect the effective opacity of the fill.

   Oh, that's right. Slipped my mind.

   I will figure that one out.

Thanks, Glynn,
