I meant to ask, if := is a statement and = is an operator in ADA or are
both operators. Statemants and operators are two different language
constructs, usable in different places.
In C both = and == are operators and results of both can further be used
in expressions, in most languages assignment is a statement not an
operator, and statements have no result.
Can you do something like "A > (B := C)" or "IF (A:=B) THEN ..." in
ADA ?
