Demy, i'm afraid the question does not make much sense to me. Can you give
a short example of what you intend to do? Oh, if its how to find out the
type of an untyped Var parameter, you cannot. It is called untyped for a
good reason <g>.

Hi Peter, first, thanks for your help..

I mean, is there a function in Delphi 1.0 that returns the type of a
variable: example

var a: string;
var b: integer;
....

a:=DATATYPE(b)

Thanks another time. Have a nice day

them... forget my question and excuse me...
