Thanks, Jim! Not a problem, But will postscript() work? I thought that help file said that only pdf and MacOSX quartz would work (at the time it was written).

It certainly does not work for me on the screen.

Btw, I made an error in writing the previous e-mail: the command to convert to .eps from .ps is ps2epsi.

Many thanks and best wishes,
