Indexing the player's initial position.

§1. Since backdrops are contained using different mechanisms, the following adds backdrop contents to a room called loc, or lists backdrops which are "everywhere" if loc is NULL.

void IXBackdrops::index_object_further?Usage of IXBackdrops::index_object_further:
Map Element - §1, §1.2
Spatial - §3(OUTPUT_STREAM, instance *loc, int depth,
    int details, int how) {
    int discoveries = 0;
    instance *bd;
    inference *inf;
    if (loc) {
        LOOP_OVER_BACKDROPS_IN(bd, loc, inf) {
            if (++discoveries == 1) Insert fore-matter1.1;
            IXPhysicalWorld::index(OUT, bd, NULL, depth+1, details);
        }
    } else {
        LOOP_OVER_BACKDROPS_EVERYWHERE(bd, inf) {
            if (++discoveries == 1) Insert fore-matter1.1;
            IXPhysicalWorld::index(OUT, bd, NULL, depth+1, details);
        }
    }
    if (discoveries > 0) Insert after-matter1.2;
}

§1.1. Insert fore-matter1.1 =

    switch (how) {
        case 1: HTML_OPEN("p");
                WRITE("<b>Present everywhere:</b>"); HTML_TAG("br"); break;
        case 2: HTML_TAG("br"); break;
    }

• This code is used in §1 (twice).

§1.2. Insert after-matter1.2 =

    switch (how) {
        case 1: HTML_CLOSE("p"); HTML_TAG("hr"); HTML_OPEN("p"); break;
        case 2: break;
    }
