#2 space before argument parentheses

[Anonymous]

Dear sir,

I try to use ruby 1.8.1 and rgplot v0.5 on HP-UX 11.0.

% ruby -v
ruby 1.8.1 (2003-10-31) [hppa2.0w-hpux11.00]

I have two problems.

(1)array_demo.rb runs well but it gives the following
messages.
Is this a problem of ruby 1.8.1 ?

/home/scat/tawada/local/lib/ruby/site_ruby/1.8/
Gnuplot.rb:81: warning: don't put space before argument
parentheses
.

.
/home/scat/tawada/local/lib/ruby/site_ruby/1.8/
Gnuplot.rb:302: warning: don't put space before argument
parentheses

(2)I would like to know how to close the gnuplot's graph.
Just kill it ?

Sincerely yours,

Tawada
