Writing the variable silences the warning, so what about
writing to /dev/null or a scratch file?  For example,

  open(666,file='/dev/null')  or  open(666,status='scratch')

  [..]

  read(8) ignore
  write(666,*) ignore ! to avoid 'set not used' warning

If the open was buried early on, this might not be too bad?
