                Shell broken on exit code 1
              
          
    If the parent script runs with fail on error switch: tcsh -e
but a sub script issue a exit code non zero.
Then the parent will fail like a Jenkins pipeline, Bamboo job or else.
This switch allows easy pipeline debug by stopping the script when exit code > 0
