args in Scheme

2011-02-15 Thread 胡海鹏 - Hu Haipeng 
Hello,
  Three years ago, when I defined a function, someone told me that in Lily 
Scheme can only take up to 3 arguments. I don't know whether this limitation is 
eliminated now, so could you tell me whether the following prints correctly?
Haipeng
\version 2.13.50
triTempo =
  #(define-music-function (parser location prependText notevaluei notevalueii 
appendText) (string? string? string? string?)
  #{ \tempo \markup { \line { $prependText  ( \fontsize #-2 \general-align #Y 
#DOWN \note #$notevaluei #1 = \general-align #Y #DOWN \note #$notevalueii #1 
$appendText ) } }
  #})
  \score {
\new Staff {
  \time 4/4
  \triTempo Allegro 2 4 = 60
  c'4 c' c' c'
}
\layout { }
  }

I believe it is correct.  With 2.13.47, I see:
  Allegro (  [half note symbol] = [quarter note symbol] = 60 )

Cheers,
