    Dear Fluka authors,

    I have run into the expiration of the 2003.1b version while in the midst
    of a critical simulation for my work. If I were simply running on my local
    machine I'd move the clock back a few days when it used to work, but I
    cannot play such a trick since I am running on a cluster.

      **** This version is obsolete and/or ****
      **** you are not allowed to use FLUKA ****
      **** Please contact Alfredo Ferrari ****
      **** INFN-Milan, tel.+39-02-503-17374 ****
      **** or look for an updated version ****
      **** at http://www.fluka.org ****

    I tried downloading the 2003.1b version on the website but it also has
    expired. Please let me know ASAP if this can be fixed. It is not
    reasonable for me to migrate to the newest version for this particular
    work since many changes occured (ie renamed variables and common blocks).

    Thanks
    Kerry

    Subject: Re: need help for source.f file

    As already pointed out by Giuseppe Battistoni, the error
    is not due to your source routine, but to the lack of a
    command BEAM in the input file defining the maximum energy
    used in the present run.
    However, I would like to call your attention on the fact that there is no
    need for a source routine in order to sample uniformly
    a starting position between two values in x and y, and an energy
    between two values.
    With a BEAM card (I copy from the manual):
    WHAT(2) > 0.0 : beam momentum spread in GeV/c. The momentum
              distribution is assumed to be rectangular
    [OK, this is a uniform MOMENTUM distribution, and not an
    ENERGY distribution, but at the energies you have mentioned there is no
    real difference]
    WHAT(4) > 0.0 : beam width in x-direction in cm, if WHAT(6) > 0.0.
              The beam profile is assumed to be rectangular.
    WHAT(5) > 0.0 : beam width in y-direction in cm, if WHAT(6) > 0.0.
              The beam profile is assumed to be rectangular.

    A few more, small remarks:
    - to "start the random number generator" you must use the command
      RANDOMIZe in the input file. The argument of FLRNDM is a dummy which is
    not used anywhere, not an initialization value.
    - the values passed to subroutine source by command SOURCE are
      called WHASOU(1), WHASOU(2), etc., not wha1, wha2 etc.
    - Subroutine source is called with only one argument (NOMORE)
      and calling it with 3 arguments can only create trouble. (I am
      surprised that your compiler did not complain). The variables
      WHASOU(1), WHASOU(2) etc. - see above - are passed via COMMON
      SOURCM, that you have correctly INCLUDEd.
