Allow character array constructors with variables of different LEN
Opened this issue · 2 comments
Some people, including me, have wished that a character array constructor with variables of unequal length
["a", "bb", "ccc"]
which is currently illegal, were treated as a character array where the LEN equals that of the element with the largest LEN, so that the above is equivalent to
["a ", "bb ", "ccc"]
or
[character (len=3) :: "a", "bb", "ccc"]
As complete implementations of the language must already be capable of evaluating every effective item in an array constructor into an expanding pool of dynamic memory in worst case scenarios -- think about an array constructor with implied DO loops with dynamic bounds, or items that are function results of dynamic shape -- this request shouldn't require too much extra work in a compiler or its runtime support library. If you could whip up a prototype in an open-source compiler as a demonstration, you might find support for this in other compilers easy to come by.
