Subroutine FINVAL Subroutine FINVAL is useful for determining the final coordinates <strong>of</strong> a particle. Subroutine FINVAL (DIST,XCOORD,YCOORD,ZCOORD) DIST : the distance traveled. XCOORD: X-coordinate after travel. YCOORD: Y-coordinate after travel. ZCOORD: Z-coordinate after travel.
Subroutine PLAN2P • The HOWFAR example that we have been following can be simplified even further with the aide <strong>of</strong> Subroutine PLAN2P SUBROUTINE HOWFAR; include ‘include/egs5_epcont.f’’ !Other includes are omitted integer irl !Other declarations are omitted IRL=IR(NP) IF(IRL.NE.23) IDISC=1 !Discard particles outside region 23 ELSE !Track particles within region23 CALL PLAN2P(7,24,1,6,22,-1); END IF RETURN END
