1.2.10 $COPERATORS : Allow C like operators

This boolean switch determines whether C like assignment operators are allowed. By default, these assignments are not allowed. After the following statement:

{$COPERATORS ON}

The following operators are allowed:

Var  
  I : Integer;  
 
begin  
  I:=1;  
  I+=3; // Add 3 to I and assign the result to I;  
  I-=2; // Substract 2 from I and assign the result to I;  
  I*=2; // Multiply I with 2 and assign the result to I;  
  I/=2; // Divide I with 2 and assign the result to I;  
end;
