Hi Vince,
I've enhanced this function in v0.56. It now looks like this ....

--------------------------
global function getLVItemText( integer id, integer item, integer subitem)
    sequence text

    --NEW! v0.56-- Added parameter validation.
    text = ""
    if    item > 0 and item <= length(lvitem_data)
      and subitem >= 0 and subitem <= length(lvitem_data[item][2])
      and id = lvitem_owner[ item ]
    then
        -- NEW! v.056-- Subitem of 0 returns all strings.
        if subitem = 0 then
            for i = 1 to length(lvitem_data[item][2]) do
                text = append(peek_string(lvitem_data[item][2][i][1]),
                       text)
            end for
        else
            text = peek_string(lvitem_data[item][2][subitem][1])
        end if
    end if

    return text
end function
