Numerous line truncations and uninitialized variables

[mlt]

There are numerous cases of truncated lines and/or uninitialized variables. It might be the cause of various misbalances.

The essense of a problem:

main.f

      program hello
      call tryme
      aaaaaaaa = 2
      a = 1
                                                                  d = aaaaaaaa
      print *, d
      end

tryme.f

      subroutine tryme
      aa = 3.
      end

gfortran main.f tryme.f
./a.out

You'll get nonsense like (may vary)

mlt@nb:~/dev/swat/master/build(master)$ ./a.out
  -1.41008350E-05

Note that -fno-automatic does not solve the problem

gfortran main.f tryme.f -Wall -fno-automatic -finit-real=snan -ffpe-trap=invalid
./a.out

The above will cause exception.
