Variable Declarations

In the following, "=" means that the variable at the left receives the current value of the expression at right, but does not depend on it any further, whereas ":=" makes it depend on this expression, i.e. every time the expression changes, the variable is re-evaluated, except for "const" variables. 
var = expression;
var := expression;
real var = expression;        // identical
real var := expression;       // to above
int var = expression;         // truncated if expression is real
int var := expression;
const var = expression;
const var := expression;
const real var = expression;        // identical
const real var := expression;       // to above
const int var = expression;         // truncated if expression is real
const int var := expression;
