To know the last record, you have read the full input stream and then in the END pattern, print out the records. Since you are using an associative array in the mentioned manner, the elements of it will always contain the last records of any group.
And, setting OFS is useless in this case.
Code:
BEGIN{FS=";"}
{array[$1,$2]=$0}
END{for(a in array) print array[a]}

NAME
viewphref - display elements of a phref_list ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in Paris, France. Web : http://asim.lip6.fr/recherche/alliance/ E-mail : alliance-users@asim.lip6.fr SYNOPSYS
#include "mph.h" void viewphref(pt) phref_list *pt; PARAMETER
pt Pointer to the phref to be scaned DESCRIPTION
viewphref scans all the primary elements of the phref_list pointed to by pt, and displays a textual output of the data strcuture contents. Its use is mostly for debugging purposes, and educational ones, since the output is quite verbose, even if very easy to understand. EXAMPLE
#include <stdio.h> #include "mph.h" void view_ref(ptfig) phfig_list *ptfig; { phref_list *ref; for (ref = ptfig->PHREF; ref; ref = ref->NEXT) viewphref(ref); } SEE ALSO
mbk(1), phref(3), viewph(3), viewphfig(3), viewphseg(3), viewphins(3), viewphvia(3), viewphcon(3). BUG REPORT
This tool is under development at the ASIM department of the LIP6 laboratory. We need your feedback to improve documentation and tools. ASIM
