* This program generates showers within a cylinder made of an
* homogeneous material.The statistics of shower profiles and
* particle's flux are computed and plotted.
* It has been used to do the GEANT/EGS comparison.(CERN/DD/85/1)
*                                               
*     The present release has been modified :            
*                                          
* - to increase the flexibility of the volume definition from
*   data cards.(see description of the common /PVOLUM/ )
*                  
* - to permit to define all kinds of primary particles,i.e electrons 
*   as well pions ( ===> hadronic showers ).
*   see data card KINE.
