Hi,

I think it may be the order in which your par() configuration occurs relative 
to png().  When you open a new device, as you have with png(), the default 
par() values for that device are exposed. If you move your par() statement to 
*after* your call to png() you get the result you desire.

S=read.table("Sarrazin-2.5",as.is = default.stringsAsFactors())
#par(tcl=0.5,las=1)   # - move to after you open the device
png(file="partest-1.png",width=580,height=580)
par(tcl=0.5,las=1)    # - configure the device after opening it
dev.control("enable") 
plot(V3,V2,xlab=" ",ylab="BIP, rel. zu Deutschland", 
pch=16,xlim=c(630,930),ylim=c(95,135))
dev.off()

See the 'details' section of ?par  - "Each device has its own set of graphical 
parameters."  I take that to mean a new set of parameters are exposed.

Cheers,
Ben

P.S.  I wonder if that sentence might have more value if it read like this, 
"Configure each device after opening as each device has its own set of 
graphical parameters."
