If I have a program like this:

------------------------------------------------------
program Project1;
{$mode objfpc}{$H+}
type
  whatever = (seth, paul, ken);
var
  haha : whatever;
begin
  haha := seth;
  writeln(haha);
end.
------------------------------------------------------

I can compile it in linux with FPC and run it and get the following output:

------------------------------------------------------ $ ./project1
seth
------------------------------------------------------

In other words, it actually prints out the name of the enumerated value.

In windows the program does not compile with an error of "Error: Can't read or write variables of this type".

Why the difference in behavior?

Different compiler version. The above is only possible as of 2.4.0.

I'm sorry, I should have realized my Windows environment wasn't as up-to-date as my Linux environment. You're absolutely right.

Thanks,
