I have a problem with source.f, which is probably simple but I have not
gotten around it after many variations. I am using it to read in a file
of beam properties, and set the variables in the stack. In addition to a
SOURCE card, I have a BEAM card with a value for WHAT(1) and for the beam
particle of interest.
The source subroutine is entered for the first particle, and I believe all
appropriate variables are set (confirmed by some inserted print
statements). Upon return, the program crashes. The .out file contains
NEXT SEEDS: 5 0 0 0 0 0 181CD

The coordinates shown are correct. I set both the particle momentum and
the kinetic energy in source. I have tried things (at least) 2 ways:
placing my values into the variables of the template routine (which are in
the BEAMCM common), and using my own variable names to set the values in
the FLKSTK common (leaving BEAMCM unchanged).
I don't know why the program thinks the energy is zero. Any suggestions
would be appreciated.
The input and source.f files (text) are attached.
