  The code SCREAM -- SuperConducting RElativistic particle Accelerator
siMulation was significantly modified and improved. Some misprints in the
formulae used have been fixed and a more realistic expression for the
vector-sum introduced. The realistic model of Lorentz-force detuning (LFD) is
developed and will be implemented to the code. A friendly GUI allows various
parameters of the simulated problem to be changed easily and quickly. Effective
control of various output data is provided. A change of various parameters
during the simulation process is controlled by plotting the corresponding
graphs "on the fly." A large collection of various graphs can be used to
illustrate the results.
