Purpose: 

 SLAMRG will create a permutation list which will merge the elements
 of A (which is composed of two independently sorted sets) into a
 single set which is sorted in ascending order.
Parameters:
[in]N1
          N1 is INTEGER
[in]N2
          N2 is INTEGER
         These arguements contain the respective lengths of the two
         sorted lists to be merged.
[in]A
          A is REAL array, dimension (N1+N2)
         The first N1 elements of A contain a list of numbers which
         are sorted in either ascending or descending order.  Likewise
         for the final N2 elements.
[in]STRD1
          STRD1 is INTEGER
[in]STRD2
          STRD2 is INTEGER
         These are the strides to be taken through the array A.
         Allowable strides are 1 and -1.  They indicate whether a
         subset of A is sorted in ascending (STRDx = 1) or descending
         (STRDx = -1) order.
[out]INDEX
          INDEX is INTEGER array, dimension (N1+N2)
         On exit this array will contain a permutation such that
         if B( I ) = A( INDEX( I ) ) for I=1,N1+N2, then B will be
         sorted in ascending order.
