# Exit Code 0 corresponds to Finish Flow
# Exit Code 1 corresponds to Output 1
# Exit Code 2 corresponds to Output 2
# and so on. Exit codes outside the defined range will be treated as a failure output.

# Example: Copy the working file to a backup location
# cp ""$WorkingFile"" ""/path/to/backup/$(basename \""$WorkingFile\"")""

# Set the exit code to 1
