I am getting the following error.

"Types of actual and formal var parameters must be identical" I was wondering if someone would be able to comment on the error and help me out a bit more. I just can't seem to get this thing right.

simple yet rather hard to find.

let's say you have something like that:

Code: Select all


procedure surprise( var X: cardinal )


and then try something like:

Code: Select all


var
  Y: integer;
begin
  surprise( Y );
end;


you'll get that error. you know why? in this example Y isn't cardinal.

what I did? hardcore types?

In addition to what Johnny_Bit said, in the above example, calling surprise function with a constant parameter causes the same problem. It's because the parameter needs to be passed as reference and should be variable.

Thanks guys for the help. The error was that it should have been passed by reference. It works now. Thanks
