Thanks. The asterick in this case and when used to initialize allocatable
character variables does not fit my old rule of thumb that "an asterick means
the variable is allocated and has a fixed length and size defined in another
scoping unit" (it is declared in the current unit); but it didn't fit my rule
about : meaning it was allocatable either. What you can and cannot do with
character variables has changed significantly; so I was not positive this was
an issue or not. I appreciate the fix and clarifications.
