Tomasz,
Cint has limitation in #define usage. Especially from the interactive interfac
e,you can use #define is such ways. It is recommended to use #define only for
#ifdef , #ifndef switch and simple constant value definition.
This is a fundamental limitation which can not be changed easily.

Use reference type variable instead.
root[3] TNtuple*& tr = ntp <<<<< instead of #define
root[4] tr->Draw("LC:Xnm")

Do not do this. Write a function and load it using .L command.
// asde.h
template<class T> T asde(T x) { return(2*x-13/x); }
root[7] .L asde.h
root[8] asde(12)
