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.)
