    Can someone tell me why tractor paper used to come in the green/white stripe variety. Thats pretty much all I remember in school in the early 80's.

    Because that eliminates all the periods:

    Item 1................................................. ............542577
    Item 2................................................. ............753257

    I wish it was still easy to get that stuff.

    For us, it was blue and white--at 10 LPI it was very useful in counting lines.

    Just make sure that your carriage control tape is correctly punched--with a punch in every column to avoid runaways.

    Also makes lines of code in huge programs easier to differentiate.

    Forms layout was a real art back in the day--I think I still have my steel forms ruler.

    Green- or blue-bar paper had alternating bars of half-inch color and no color, with the top inch no color and the bottom inch uncolored as well.

    Common spacings on line printers were 6 and 8 lines per inch. That means that, allowing for a perforation skip at bottom of page, there were 63 lines at 6 lpi (3 lines per bar) and 84 lines (4 lines per bar) at 8 lpi.

    I don't think the bars were ever designed for the exclusive use of programmers--in fact, I generally reversed the paper for program and dump printout to avoid the distraction of bars. I think they certainly helped the accounting types.

    Coding forms were also often produced in the "barred" format.

    I prefer it for programming, maybe I'm alone in that.

    This type of paper formatting (bars) was also common for non-computer forms.
