phythia random number seed

[Blake Leverington <leverinb@uregina.ca>]

Hi,

Is anyone aware of where to give Pythia a new default initial seed for 
the random number generator at runtime? I want to create a large 
background data set but I'm limited to around 2 million events due to 
file size limitations. Therefore I want to make multiple Pythia output 
files but repeated runs of Pythia seem to give me identical data sets 
which seems to be from having the same initial seed for generating 
random numbers. I checked the pythia6 manuals but didn't have much 
success on where to set this. If anyone is more familiar with this it 
would be appreciated.
