There error is somewhere in the bundle below ( of the script
getScriptingNewsXml) - four urls are being returned and only 3 pieces of
text for the links:

on extractLinks (s, adrLinks, adrLines) {
    local (links = {}, lines = {}, pat = "<a href=\"", ix, leftHalf);
    s = html.processMacros (s, true, pta);
    loop {
        ix = string.patternMatch (pat, s);
        if ix == 0 {
            break};
        leftHalf = string.mid (s, 1, ix - 1);
        s = string.delete (s, 1, ix + sizeOf (pat) - 1);
        ix = string.patternMatch ("\"", s); //the end of the url
        url = string.mid (s, 1, ix - 1);
        s = string.delete (s, 1, ix);
        ix = string.patternMatch (">", s); //PBS 11/1/00: find end of
opening a tag
        s = string.delete (s, 1, ix);
        if s [1] == ">" {
            s = string.delete (s, 1, 1)};
        ix = string.patternMatch ("</a>", s);
        lineText = string.mid (s, 1, ix - 1);
        s = s - "</a>";
        s = leftHalf + s;
        links = links + url;
        lines = lines + lineText};
    adrLinks^ = links;
    adrLines^ = lines;
    return (s)}

 Is this a bug? If so can someone look into it please.

Thanks,
Jim
