JAM:update note

jam1.012   Sep. 16 2003
 bug fix pointed out by T.Tabaru(RIKEN)
 for the generation of soft pt kick.  pt kick was generated
 randomly from the prepared tables, but it was not smooth enough.

jam1.011.00   Jul. 17 2003
  bug fix in subroutine jamwidm in jamdec.f
  after version 1.009.28  pointed by Ryotaro Muto (Kyoto)
  decays were forbiden when resonance pole mass is less than the sum
  of daughter particles in the case of momentum dependent decay width.
  For example, a0/f0 -> KK channels.

jam1.010.01   Feb. 23 2002
bug fix in jamsoft.f, jamhard.f,jamhij.f  pointed out by Tsuguchika TABARU
  <The result has not been changed in this bug.>
 The information which contains in indd() was wrong. So one gets
wrong information in each string decay in the case that one of decay
products is anit-baryon.  In the case of hard scattering, this
bug is still not removed. If one wants to know the information
for each collision and decay, please ignore partons in the
information. 
jamhij.f
    call jamerrm(30,'(hifun:) This number already used'//code)
--> call jamerrm(30,0,'(hifun:) This number already used'//code)

jam1.010.00   Jan. 04 2002
bug fix in jamdec.f pointed out by Tsuguchika TABARU
      totwid1   = totwid / paru(3)
-->
      totwid   = totwid / paru(3)
(older version < jam1.009.24 is ok)

jam1.009.29   Jan. 10 2001
 bug fix  in jamhij.f at entry vegas2(fxn,avgi,sd,chi2a)

7     continue
        xi(nd,j)=one
 --->
        xi(nd,j)=one
7     continue
 

jam1.009.28   Aug. 31 2000
 1. add dummy subroutine jamanaus to be able to analyze something
    at each collision and decay by users.

jam1.009.27   Apr. 21 2000
 1. update particle data: short lived particles do not decay as a default.
 2. slight modification of code to handle option 'user'.
    To know how to use the option frame="user", main program of main_blz.f
    and mainu.f would be useful.
 3. update jam.tex to explain how to use frame='user'.

jam1.009.26   Apr. 2000
 1.  Add new option 'user' for input variable frame.  This allows for user
     specified phase space data for the initial condition of cascading.
     If frame='user', you have to fill the following common bock.
      common/jamevnt1/r(5,mxv),p(5,mxv),v(5,mxv),k(11,mxv)
      common/jamevnt2/nv,nbary,nmeson
      common/jamjet1/vq(10,mxv),kq(2,mxv)

 2.  add function  'jamflav' that gives baron number or flavour content
      of particles.
 3.  bug fix: no effect on random number seed when input file is used
