Kat,

Have a look at the routine below. Is it what you wanted?
You will need Gabriel's pretty print include for a prettier output.

include print.e     -- Gabriel's extension

function strip(sequence s)
--  return sequence s with empty substrings removed
    sequence v,si

    v = {}
    for i=1 to length(s) do
        si = s[i]
        if length(si) then
            v = append(v, si)
        end if
    end for
    return v
end function

function mesh(sequence s)
    sequence u,v
    integer n

    n = length(s)
    for i=1 to n do
        s[i] = strip(s[i])
    end for

    v = {}
    for i=1 to length(s[1]) do
        v = append(v, {s[1][i]})
