   Not at all, the 1X means that the line-feed character is a space.  A "+"   
   there would probably overlay whatever had previously been printed to   
   that line with something new.   
   I have used several different compilers on several different   
   architectures over the years (the newest adhered to the F77 standard)   
   and the meaning of the first character on a line was common to all of them.
