SLAMRG creates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.

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.
