Read data and append it to array, best practice?

@RonShepard

So why does the standard not allow the simple array notation in this case?

I have actually given the reason above:

@PierU

Because this syntax defines an array of allocatable characters, which is not allowed.

More precisely an array of allocatable characters is not allowed because each element can have a different storage size, which would mean a non constant stride.
