I thought this might be useful for us since HiJing is so popular at the moment.

Hi All!

Giorgos Stavropoulos (ATLAS collaboration), who is using C++ interface to 
the HIJING model, has found a bug in the HIJING model. In all HIJING 
documentation it is saying that a user has to call 

      CALL HIJSET(EFRM,FRAME,PROJ,TARG,IAP,IZP,IAT,IZT)
C                       ********Initialize HIJING
where 
      CHARACTER FRAME*8,PROJ*8,TARG*8

At the same time, the variables, FRAME, PROJ, TARG, are described in the 
HIJSET subroutine as

      CHARACTER FRAME*4,PROJ*4,TARG*4,EFRAME*4

These can lead to an unpredictable error. In order to protect the error, 
you have to replace the previous line by the new one in the HIJSET 
subroutine.

        CHARACTER FRAME*8,PROJ*8,TARG*8,EFRAME*8

A version of the HIJING model corrected for found bugs is located at 
GENSER, realese 0_0_3, hijing, 1_383b. See

Sincerely yours,
