Here, it looks as if you mean passing a character string of length 1 as
a variable length string. Certainly, this should be no problem. Pardon
me if I misunderstood.
In either case, there should be plenty of references in c.l.f archives.
In general, passing a scalar where an array reference is required is
non-standard and a serious portability issue. Use of module or
interface syntax should cause any problems to be diagnosed.
For CHARACTER type, there is a distinction between an array (of
character strings, possibly of length 1) and a scalar character string.
