///Quick question for the OP...are the files sorted and the records are guaranteed in the same order? Otherwise, what's the key to tie the records? I ask since your initial evaluation seems to focus on flags like chr1...///

Thank you very much guys. I did not expect such quick responses. Somehow I did not get email alerts too.

To answer your question, file 2 is sorted by 'chr' (ascending) and file 1 is sorted by field 1 (ascending). I have not tried the code given here yet. I will check it out.

Thanks a ton you guys - you rock.

oopsy - file 2 is sorted by field 1 and file 1 is sorted by chr (chr1 to chr19).

Sorry being so dumb but when i execute this code in my xp computer, i am getting all kinds of errors like " the system cant find the path specified", and at s=$11^ unexpected newline or end of a string found" . Can you please tell me where am I doing wrong? thanks.

slamrg.f(3)							      LAPACK							       slamrg.f(3)

NAME

       slamrg.f -

SYNOPSIS

   Functions/Subroutines
       subroutine slamrg (N1, N2, A, STRD1, STRD2, INDEX)
	   SLAMRG creates a permutation list to merge the entries of two independently sorted sets into a single set sorted in ascending order.

Function/Subroutine Documentation
   subroutine slamrg (integerN1, integerN2, real, dimension( * )A, integerSTRD1, integerSTRD2, integer, dimension( * )INDEX)
       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:
	   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 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.

	   STRD1

		     STRD1 is INTEGER

	   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.

	   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.
