error passing compound strings to system command

[<pl...@pi...>]

Hi,

I appear to have hit a limitation on setting up a command string for  
system command. I have a "simple" bash command line that works in a  
terminal:

bash-3.2#tail -n1 "../htdocs/data/adc.data"| awk 'format= " c3=%g\n  
c4=%g\n c5=%g\n" {printf format,$3,$4,$5}' >temps.tmp
bash-3.2#cat temps.tmp
  c3=1.796
  c4=1.676
  c5=2.788

However, when I try to replicate this from within gnuplot is seems not to  
get correct send to awk


   system "tail -n1 '../htdocs/data/adc.data'| awk 'format= \" c3=%g\n  
c4=%g\n c5=%g\n\"  {printf format,$3,$4,$5}' >temps.tmp  "

awk throws an error back to gnuplot:

gnuplot> load "control.gnu"
awk: format= " c3=%g
awk:         ^ unterminated string


For some reason it seems not to see the second \"
I have tried to rearrange this in different ways but it always seems to  
hit the same root cause.

Is this a possible bug in the parser?

Thx, Peter.
