Re: tripping over filehandle / subroutine usageby LanX (Saint) |

just a guess: if your FH is at EOF after the first subroutine you should reset the position to start using seek before expecting to read again in another sub. UPDATE: ok, now that you updated code it seems like my guess was right: my @rows = (<$input_handle>); exhausts your filehandle. BTW you should consider working with something like to read line by line, when working with large files, because otherwise you're consuming lots of RAM.
