Excellent! Here's implementations for the lores functions plot(), 
hlin(), & vlin(), as well as a small demo:

// Lores test by John B. Matthews

blockWidth = 16; // screenWidth / 40
blockHeight = 10; // screenHeight / 40

hgr();
print("Lores test");
draw1();
animate(draw2);


function draw1() {
    for (p = 0; p < 39; p++) {
        hcolor = rnd(15) + 1;
        plot(0, p);
        plot(p, 0);
        plot(39, p);
        plot(p, 39);
        plot(p, p);
        plot(39 - p, p);
    }
}

function draw2() {
    x1 = rnd(40);
    y1 = rnd(40);
    x2 = rnd(40);
    y2 = rnd(40);
    hcolor = rnd(15) + 1;
    hlin(x1, x2, y1); hlin(x1, x2, y2);
    vlin(y1, y2, x1); vlin(y1, y2, x2);
}

function plot(x, y) {
    rect(x * blockWidth, y * blockHeight,
        blockWidth, blockHeight)
}

function hlin(x1, x2, y) {
    if (x1 <= x2) rect(x1 * blockWidth, y * blockHeight,
        (x2 - x1 + 1) * blockWidth, blockHeight);
    else rect(x2 * blockWidth, y * blockHeight,
        (x1 - x2 + 1) * blockWidth, blockHeight);
}

function vlin(y1, y2, x) {
    if (y1 <= y2) rect(x * blockWidth, y1 * blockHeight,
        blockWidth, (y2 - y1 + 1) * blockHeight);
    else rect(x * blockWidth, y2 * blockHeight,
        blockWidth, (y1 - y2 + 1) * blockHeight);
}
