Printer plot of the Beam Envelope

Each single printout of the system requires at least the same amount of time than the calculation of the system, therefor the commands should be used with caution. A printer plot is produced of the optical system under consideration as well as of the calculated first-order envelope of the real beam (together with a beam formed by trajectories that start from a point source under angles A and B) by the command: 5 P(RINT) B(EAM) <number of printer lines> <shown maximal x-width in meter> <shown maximal y-width in meter>  ; [example: P   B   100   0.15   0.15 ;] [P   B   100   0.10   0.10 ;]

This command may occur only once.
