Abstract
An interactive code for the analysis of nonlinear area-preserving mapp ings is described; several facilities allow the user to draw phase por traits, make zooming, and use colors. The perturbative approach of nor mal forms and all the standard tools for the analysis of the nonlinear dynamics (Fourier spectra, Lyapunov exponents, fixed points...) are i mplemented in a user-friendly graphic environment based on X-window an d OSF-Motif. Both simple models and more involved mappings which descr ibe the betatronic motion in a particle accelerator can be implemented .
