In general, it is necessary to know the length of a string in Fortran before using it. There is no general string with unspecified strength. Some libraries do provide such an object (e.g. Fortran Standard Library, but it is not available in the standard language. To obtain the length of the string in your example, you could use the length option in get_command_argument as integer :: clen character(len=:), allocatable :: string_b call get_command_argument(2, length=clen) allocate(string_b(clen)) string_b = '' call get_command_argument(2, string_b) write(*,*) string_b deallocate(string_b)
