OK for the trunk?

Looks mostly OK, but I have one question: I donât understand what the wording "Type IMPLICIT NONE statementâ is supposed to mean. Why âtypeâ?

Well, I want to distinguish "IMPLICIT NONE (external)" which onlyapplies to procedures from "IMPLICIT NONE" alias "IMPLICIT NONE (type)"which applies only to variables and function (return value) types. Thus,

  IMPLICIT NONE (external)
  IMPLICIT integer(a-z)
is valid while
  IMPLICIT NONE
  IMPLICIT integer(a-z)
is not.

If you have a better suggestion for the wording â

Tobias
