This all works EXACTLY as intended.use strict; use warnings; #convert DDHHMM into int of m sub d2i { my( $d, $h, $m ) = unpack '(A2)*', $_[0]; return ( ( $d - 1 ) * 24 + $h ) * 60 + $m; } #convert int of m into DDHHMM sub i2d { sprintf "%02d%02d%02d", int($_[0]/1440)+1, int($_[0]/60)%24, $_[0] +%60; } #find and open files ... only ever 1 of each file type my ($d,$t); foreach (<*>) { $d = $_ if (/\.dat$/); $t = $_ if (/\.mrg$/); } open(D, $d) or die "Unable to open DAT file.

As you can also see, there is no 'year' date tag in input files, so there is still an assumption being made about DEC->JAN rollovers too.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa f sd fa sdfasdf /XXX/XXX/300000ZSEP/020000ZOCT/XXX/XXX a sdfasdfasdf asdf df sa fas dfASDFASDF AS DF ASDF SDFASDF /// //sdfasdf/123 \\ /asdfasdf adsf sdf// /555/234/ /301222/301232/234/4234/011.0/ /fasdfasd /301240/301250/asdf/fdsa/011.3/ /302340/302355/9j9js9j9j9jf9sjfd/9j9sfj9df9323/010.0/ /302359/010002/kfjakdjfakdfasdf/salkdjfaklsdjflkasjd/008.1/ /011200/011400/kfjakdjfakdfasdf/salkdjfaklsdjflkasjd/008.1/ asd /1/2/3/4/5 // /
