   I remember using  a later C compiler that accepted   
   the older form of assignment operators, such as =+, =-, etc.   
   Presumably for those with older code.   
      
   I then had to put an extra space when assigning negative values:   
      
      i= -4;   
      
   I don't remember now how I found out about that one.   
      
   That is the only old C syntax I remember.   
   (And much later than 1975.)
