I agree with pludi. If you have more than one array, or even really just one array, use references as I showed in my other post. As far as @_ goes, he explained it well enough so I will leave it at that.

dlamrg
dlamrg.f(3) LAPACK dlamrg.f(3)
NAME
dlamrg.f -
SYNOPSIS
Functions/Subroutines
subroutine dlamrg (N1, N2, A, DTRD1, DTRD2, INDEX)
DLAMRG
Function/Subroutine Documentation
subroutine dlamrg (integerN1, integerN2, double precision, dimension( * )A, integerDTRD1, integerDTRD2, integer, dimension( * )INDEX)
DLAMRG
Purpose:
DLAMRG 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:
N1
N1 is INTEGER
N2
N2 is INTEGER
These arguements contain the respective lengths of the two
sorted lists to be merged.
A
A is DOUBLE PRECISION 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.
DTRD1
DTRD1 is INTEGER
DTRD2
DTRD2 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 (DTRDx = 1) or descending
(DTRDx = -1) order.
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.
