That how we "isolate" the relevant numerical (!) sort field from the rest of fields that are considered strings. We're lucky here in that sort seems to disregard the .ts extension when extracting / calculating the numerical field.

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.
