how difficult would it be to add execution of strings to interpreter?
i know i can use some mathematical expression evaluator, but what if i =
need to call some of my functions or something similar.
something like this:
integer i
i =3D evaluate ("(1+2)*pow(3,2)")
i is now 27

There are a couple interpreters in the archives.

What is this EU scripting language you're talking about?
I should be more specific: I was asking about how difficult would it be to
add it to C source code of interpreter to become part of Euphoria language.
Scripted languages usualy have this feature (JavaScript: eval (), VBScript)
and in my opinion this is one of advantages of interpreted (scripting)
languages over compiled languages. I don't know why Eu doesn't have it?
I'm thinking it should be pretty simple, you should just treat it as another
include. Someone with source code?

Would you be happy if you could write out the string to eval, into an .e file,
and call a batch file to eval(file.e) ?

I need to do this in a loop and you can't include files in a loop.
