Hi,

Sorry to bother you so much. I think I found a bug: running ./test_basic --string hello gives me

...
Integer list inputs:
  Input(1) = +1
  Input(2) = +140308968915872
  Input(3) = +140734567466896
...

Whereas the default values are 1 8 32. If I add --integer_list 1 2 3 everything works fine. I tracked it down, and it seems that the default separator 'args_sep' is not inserted into the default list. I could fix it by replacing

call tokenize(strin=buffer, delimiter=args_sep, toks=vals, Nt=Nv)

with

  if(.not.self%is_passed) then
    call tokenize(strin=buffer, delimiter=' ', toks=vals, Nt=Nv)
  else
    call tokenize(strin=buffer, delimiter=args_sep, toks=vals, Nt=Nv)
  endif

But that is probably not a good way of doing it. I tried figuring out the parse sobroutine, but my brain started hurting when I tried to figure out what to add.
