File position inquiry with non-advancing formatted stream access and sheep

I've never been good at poetry... so I've started using Fortran to help me. Getting the right number of syllables in each line has always been tricky, so sometimes I skip over bits, and then fill them in later.

PROGRAM poetic_streaming
  IMPLICIT NONE
  
  INTEGER :: unit
  INTEGER :: pos
  
  OPEN(  &
      NEWUNIT=unit,  &
      FILE='poetry.txt',  &
      FORM='FORMATTED',  &
      ACCESS='STREAM',  &
      ACTION='WRITE',  &
      STATUS='REPLACE' )
  
  WRITE (unit, "(A)", ADVANCE='NO') 'Mary had a '
  ! Remember where we are and leave a placeholder for now.
  INQUIRE(unit, POS=pos) ; print *, pos
  WRITE (unit, "(A7)", ADVANCE='NO') ''
  WRITE (unit, "(A)") ' processor'
  
  WRITE (unit, "(A)") 'ifort was its name'
  WRITE (unit, "(A)") 'but support for querying the file position after non-advancing formatted stream access output was broken'
  WRITE (unit, "(A)") 'so she had to rethink her game'
  
  WRITE (unit, "(A7)", POS=pos, ADVANCE='NO') 'Fortran'
  
  CLOSE(unit)
END PROGRAM poetic_streaming

Alas...

I think I spy a stray newline in there too.

Baaaa-d. We'll haul out the shepherd's crook for this if need be.
