      SUBROUTINE ANALYZE(SCRATCH,A)
C
C ANALYZES INTERNAL COORDINATE STRUCTURE, OBTAINS NUMBER OF
C CONFORMATIONAL DEGREES OF FREEDOM AND CHECKS FOR OBVIOUS
C REDUNDANCIES AND POTENTIAL ERRORS IN THE Z-MATRIX INPUT.
C SCRATCH IS THE SAME VECTOR USED IN SUBROUTINE SYMMETRY.
C THIS REQUIRES THE TRANSFORMATION MATRIX FROM CARTESIAN
C DERIVATIVES TO INTERNAL DERIVATIVES, AND USES A SIMPLE
C TOTALLY SYMMETRIC PROPERTY (CLOSELY RELATED TO THE NUCLEAR
C REPULSION ENERGY) AS A REFERENCE FUNTION.  NORD IS A AN
C INTEGER SCRATCH ARRAY USED ONLY HERE AND IN DEPENDENTS.
C
C This routine is cleaned up to generate messages that
C make sense for redundent internals. Some of the analysis
C done here is not useful for RICs (not valid).

c This common block contains the IFLAGS and IFLAGS2 arrays for JODA ROUTINES
c ONLY! The reason is that it contains both arrays back-to-back. If the
c preprocessor define MONSTER_FLAGS is set, then the arrays are compressed
c into one large (currently) 600 element long array; otherwise, they are
c split into IFLAGS(100) and IFLAGS2(500).
