Hi, I need to use an output parameter in an Ada function, something like

function ReadChar(f: File; c: out character) return boolean;

The function must return a boolean, so the only way to read the character is
via the 'c' parameter. In other context, I use

function (something: tpSomething) return ...; where tpSomething is an access
to a record type, and I can modify the contents of the record in the
function, but if I use

function ReadChar(f: File; c: access character) return boolean;

the compiler gives an error when i do something like

c:=anything;

Is there any way of using c as an output parameter?

Thanks.
