? RPL/HP-48 - numerical S on a << >> integrand ?

[OlidaBel]

Thanks Joe & Werner,
I finally succeeded (and understood!) how to play with integrals S onto programs. I could adapt my old 28S program and results are now OK.
The 48GX is definitely different than a 28S, it was not easy to troubleshoot ;-).
Starting with an algebraic expression and playing with local variables in <<...>> was the key.
