Here's a quick kluge that deals with some of the apparent problems, but
introduces a whole heap of others ;) ...:

-- Warning! No error or bounds checking in this code!
sequence in, outseq
integer out
in = {1, 23, 456}
outseq = ""
out    = 0  -- want this to be 123456

for i = 1 to length(in) do
    outseq &= sprintf("%d", in[i])-'0'
end for
for i = 1 to length(outseq) do
    out = out * 10 + outseq[i]
end for

? out
