Hi everybody,
I want to execute some String without writting code.
In Javascript, i can do this.

I want to know if an equivalent function exists in upp.

I see two simple ways to do this, but as Mirek said, it depends a lot on the string content.
First option is Esc, U++ native scripting language. It is similar to C, with few interesting distinctions (see help for details).
Second option is compiling C code in the string on the fly, using TCC (turbo C compiler). There is a package with examples in bazaar.
Both methods allow for binding native C++ functions into the executed code/script.
You could also use 3rd party bindings for Lua, Python, etc... but since you asked for native U++ solution, I guess that is not what you want 
Best regards,
Honza
