I need a Delphi function which I put a string and execute that...

I don't know if is possible to do in Delphi...

Delphi isn't interpreted, and doesn't include its
compiler in its exes.

You would have to ship Delphi with your application,
generate a DLL arround your source, compile it with
Delphi command line compiler, and load that DLL.

Alternatively, there should be various scripting
components arround (some even with Delphi as language),
but i don't have experience with these and don't know
at which level they allow acces to the rest of your
application.
