How to make lines of text appear on screen, one after another?

So I'm tinkering with a DOS-display-style screen, as shown below:

Code: Select all

screen wall4_reconstruct():
    zorder 1

    frame:
        pass

    vbox:
        xmaximum 1000
        align (0.1,0.1)

        text "-- {b}Re:{/b}CONSTRUCT --":
            font "fonts/SourceCodePro-Regular.ttf"
            size 30
            slow_cps 24
        text "——————————————————————————————\n":
            font "fonts/SourceCodePro-Regular.ttf"
            size 30
            slow_cps 24
        vbox:
            align (0.2,0.1)
            text "Main Subsystem: {b}Active{/b}"
            text "Files indexed for viewing:\n* /017/{b}awakening.rcs{/b}\n* /013r/{b}departure.rcs{/b}"
            text "Repurposing: {b}ui{/b}, {b}quick_menu{/b}, {b}renpy.notify(){/b}...":
                font "fonts/SourceCodePro-Regular.ttf"
                size 18
                color "#FFFC"
                text_align 0.0
                slow_cps 24

Now, what I'm trying to do is, when this screen is displayed, make the last three text elements appear one after the other. Does that require the use of the timer, or do I need something else?
