[Q-e-developers] Rev13108

[Martin Schlipf]

Dear Paolo,

I noticed the recent commit where you state that zero-length strings are
forbidden by the Fortran standard. This restriction has been removed from
the standard with Fortran90. Fortran2003 even allows for dynamically
allocated strings

CHARACTER(:), ALLOCATABLE :: string
string = ""
WRITE(*,*) LEN(string)  ! prints 0
string = "a"
WRITE(*,*) LEN(string)  ! prints 1

Best,
Martin
