What is the way to write nice error out, on any style of program?
I remember some function that gave errors properly no matter what style of program: GUI,
So on a console, the error message would be a writeln, but on a GUI program the error would
be a showmessage style error. All this handled automatically by the wrapper. Just can't put
my finger on where I saw this function and in which units.
i.e. It's time I stop using writeln calls for errors, because that just isn't the portable
way to do it.
In fact not just for abrupt and abnoxious errors, but simple polite notifications too.
