If you mean that dividing languages into 'compiled languages' and
'interpreted languages' is making a false distinction, then I would

If you mean that compilers and interpreters are much the same thing, I
strongly disagree; I think there's a clear distinction.  An
interpreter runs programs written in a particular language, whereas a
compiler translates programs from one language into another.  A
processor (possibly together with support code from an OS) is an
interpreter for a particular machine code.  So eventually every
program must be run by an interpreter.

Sure - they combine the interpreter and compiler in one program.
That doesn't mean that you can't identify two different things
happening in that program.

Also, scripts are written in high-level languages, and their source is
used directly rather than being compiled before use.

But a script *is* a program, as you said above, so they would be
correct and your nit-picking would be unjustified.

Any opinions expressed are my own and not necessarily those of Roundpoint.
