[Gnuplot-bugs] "can only mod ints" message leaves beginners high and dry

[Dan J. <ji...@ji...>]

Just want to let you know that the manual is no help when the user is
confronted with
gnuplot> plot x%10
         can only mod ints
gnuplot> plot int(x)%10
but that is not what the user wants. Alas, he must do
$ seq 18|perl -wnle 'print $_," ",$_ % 10'> /tmp/l
$ gnuplot
gnuplot> plot '/tmp/l'
Therefore in the manual at
   (*) Starred explanations indicate that the operator requires integer
       arguments.
mention what to do. Also say so in the error message above.
P.S., I see some HTML in Info on Debian:

It isn't?  And why, pray tell, shouldn't it be?

It can't possibly do that --- because it doesn't know what, exactly, is 
the right thing a user should do.
