Examples¶

agents.txt:

ID,age,sex
123,13,0
456,25,1
789,42,1
999,33,0

main.fred:

simulation {
    locations = none
    default_model = none
    start_date = 2020-Jan-01
    end_date = 2020-Jan-01
}

variables {
    shared list new_agents_list
}

condition PrintCSV {
    start_state = Agent_Start
    meta_start_state = Meta_Start

    state Meta_Start {
        new_agents_list = read_agent_file(agents.txt)
        read_agent_file(agents.txt)
        open_csv(out.txt,"id","sex")
        wait()
        next()
    }

    state Agent_Start {
        print_csv(out.txt,id,sex)
        wait()
        next()
    }
}

The above FRED code prints the following file:

out.txt:

id,sex
123,0
456,1
789,1
