   NBLKPRF.C  Number of Blocks and Profiles

      These are a pair of routines (used by LSTBLOCK) that
      return the number of profiles in the current block,
      and the number of blocks in an open database.

   FUNCTION: BPCMP

      It compares two BLKPRF_INDEX_TYPE structures/arrays.

      Note:  This is a block-profile version of TIMCMP but the
             return values have been modified for easier testing =
             signof(bp1 - bp2)

   PARAMETERS:  bp1 = pointer to first block-profile index
                bp2 = pointer to second block-profile index

   RETURNS:  -1 if bp1 < bp2
              0 if bp1 = bp2
              1 if bp1 > bp2

   CALLED FROM:  C, FORTRAN
