[Gnuplot-info] why this comment does not work properly?

[Jon <dev...@gm...>]

Dear All,

Wish you a happy New year first!

I tried to plot something like the following (noticing the comment on the
5th line)

p fil.'L10000' u 1:s w l ti 'AA N=10^{4}', \
  fil.'L100' u 1:s w l ti 'AA N=100', \
  fil.'L16' u 1:s w l ti 'AA N=16', \
  fil.'L8' u 1:s w l ti 'AA N=8', \
######  fil.'L8' u 1:s+7 w l ti 'GWF N=8', \
  fil.'L10000' u 1:s+7 w l ti 'GA'

But it complains "invalid character \" at the end of the 4th line.

This seems to me that comment within plot statement cannot be recognized,
is this really the case?

Thanks,
Jon

More to the point, comments inside a continued line won't do what you 
expect.  gnuplot behaves the same as just about every Unix-style command 
line scripting language supporting '#' comments and '\' line 
continuation does: first, line continuation is resolved, resulting in a 
single long line.  Then comments are evaluated.

So comments inside a continued line will turn off everything following 
the '#', including stuff on later lines.
