My bad... Didn't cover the case of several numbers in a row missing from the
middle of the sequence. This fixes that.
function CheckList src
sort items of src numeric
put "," into dups
put "" into miss
repeat with a = 1 to item 1 of src - 1
put a & "," after miss
end repeat
repeat with a = 1 to the number of items in src - 1
if item a of src = item a+1 of src and ("," & item a of src & ",")
is not in dups
then put item a of src & "," after dups
put 1 into b
repeat while item a of src +b < item a+1 of src
put item a of src + b & "," after miss
add 1 to b
end repeat
end repeat
return item 1 to -1 of miss & return & item 2 to -1 of dups
end CheckList
