Yes, I found it after sending my mail too.  I compared 'x07c.c' with
'x07c.m' and then I recognized it.  The fix is to change the call
        plfont(1)
into
        plfontld(1)
not adding.  Then it works.

Hmm:
        title("#gS#u5#d#b#dn=1#u"); plot(sin(1:10))
gives a small window with a nice title and the plot.

And
   global pldevice = "xwin";
   plsdev (pldevice);
   plinit;
   plmtex ("t", 1.0, 0.5, 0.5, "#gS#u5#d#b#dn=1#u"); plot(sin(1:10))
   plend
gives it on a X11 window.

Doing this I recognized the X-window does not remeber its contents.
Part of the grafic is lost if some parts of the window are in the
background and one puts the window after plotting into the foreground.

OK!  Can you meil me the name of the plplot list please, thanks.

I looked at the sources of 'octave-2.1.13' the file 'ov.h'.  It does
not contain a conversion of 'int'.  Perhaps the class 'octave_value'
should be extended to contain 'octave_value (int i)' ot something
similar.

And another hint for the '.m' files:
I think it would be an improvement to change them in a manner to make
it work with 'whitespace_in_literal_matrix="ignore".  This is, add some
missing commas and semicolons.
