line styles

[Toni Mira <toni.mira@xxxxxx>]

Hello,

I'm plotting several lines (all of them black) together and I would like 
to draw
the different available styles: SOLID, DASHED, DOTTED, DASHED-DOTTED,
LONG DASHED and DASHED AND DOUBLE-DOTTED.

I've used the PLOT/DASHED(DOWN1,UP1,DOWN2,UP2) option, but I think
It should be an easier way to do it.
Could it be possible to do it with the PLOT/ command? How can I do it?

Thanks.

Toni
