Suppress Bar lines

[Richard Downing]

Hi,

Sorry about the newbie question.  I need to suppress all bar lines (except those explicit with /bar).  I have tried adding automaticBars, e.g.:

\version "2.12.3"

\score {

    \new StaffGroup \relative c''  {

\set automaticBars = ##f

c4 d e c c d e c

        c d e c c d e c c1

      

    }

}

to a score, but this seems to have no effect.  I am probably putting it in the wrong place, or have the syntax wrong.  Could some kind soul give me an example.

Richard.
