Tony,

  I've managed to build and Pandora_Pythia on a Solaris box at SLAC w/
very minor modifications to Masako's instructions. I'm now trying to
read in and analyze the generated events in JAS through the output
STDHEP file, but I get the following exception

  java.lang.ArrayIndexOutOfBoundsException: 4000
	at jasext.hepevt.HepEvent$HepEnumeration.nextParticle
	at hep.lcd.util.driver.LCDHepEvent$MCHepParticle.getDaughters
	...

It happens on 97/100 events that I generated w/ the following

  gen_eetottbar output.dat 100 > output.list

from the examples. The Pandora_Pythia output summary looks fine (see
below), and STDHEP doesn't complain, i.e.


          ********************************************************
          *       STDHEP version 4.07  -  July 14, 1999          *
          ********************************************************


 STDXWOPEN WARNING: I/O is initialized for stdhep only

          STDXEND:     513431 words i/o with    10012 efficiency
