use only one page (a5)

[Andreas Gemperle]

Hello

I use lilypond for 2 days now, so I'm really new to it. I try to rewrite a 
short march on a a5paper-size. I have to write about 8 systems and I'd like 
to have them all on the one page, but I don't get it.
At the moment it looks like this:

######################
\paper {
#(set-paper-size "a5" 'landscape)
}
#(set-global-staff-size 11)

  \header {
  
    title = \markup \center-align { "San Carlo" } 
    composer =  \markup \center-align { "Oscar Tschuor"}}

\version "2.6.3"


melody = \relative c {
        \clef bass
        \key bes \major
        \time 2/4
     
        f4->\f a8 c8 f,4-> a8 c8 f, f16 f f8 f8 f8 r r4 \repeat volta 2 { 
bes\mf f8 d' bes2-> bes,4 d8 g f2-> f8 es c es \break 
        f8 es f a bes bes f d bes2^>\> bes'4\! f8 d' bes2^> es,4 d c2 f4\f f a 
f bes8 
bes f d} \alternative{ { bes r r4 } { bes8 r bes'\f a } } \break
        \repeat volta 2 {g2\f( g8) a bes c d2~ d8d c bes a4 d, bes' a g2( d8) r 
bes' 
a g2~ g8 a bes c \break
        d2~ d8 d c bes a r d4^>~ d8 r bes4} \alternative{ {g2( g8) r bes a} {g 
r r4 
f8_. es_. d_. c_.} } \break
        
\key es \major
        es8^\markup {\bold Trio} r es r es r r4 es'4\p( d c bes g8) es g bes 
es,2 es8 
r bes r es r bes r \break
        f' bes, d f bes2 f'4( es d c bes)
     }
     
     \score {
        \new Staff \melody
        \layout { }
        \midi {}
     }
#####################


I tried it with something like this....

     \paper {
       between-system-padding = #0.1
       between-system-space = #0.1
       ragged-last-bottom = ##f
       ragged-bottom = ##f
     }

... but i always get a syntax error like:

san carlo.ly:3:7: Fehler: syntax error, unexpected '-', expecting '='
between
       -system-padding = #1

I don't know what to do, so can you help me?

Thank you
Andi
