TRPLIS, NTRP1, NTRP2, TRPINC, Opt
Lists the particle flow or charged particle trace points.
NTRP1, NTRP2, TRPINCList points from NTRP1 to NTRP2 (defaults
to NTRP1) in steps of TRPINC (defaults
to 1).  If NTRP1 = ALL, NTRP2 and TRPINC are
ignored and all trace points are listed.  If NTRP1 =
P, graphical picking is enabled and all remaining command fields are ignored
(valid only in the GUI).
OptOpt = LOC lists the trace point
number location (X, Y, Z). Default.
Opt =
