Thank you, Allin; this works.
What I am wondered aboit ist that on Linux the error message is much
clearer and helpful than on Windows. The one linux is:
<ERROR>
plot \
^
"/home/artur/.gretl/gpttmp.LQy4tc", line 25: invalid character \
*** error in function DMplot, line 53
> gnuplot
</ERROR>
The one on Windows was not really helpful. But I guess this is
gnuplot-related, right?
Not so much gnuplot-related as an operating system issue. Gnuplot produces
quite informative error messages on stderr. These are easy to capture on
unix-type systems, but basically Windows doesn't do stderr. There are some
avenues we could explore to get hold of the messages, but they're
complicated.
