Re: index for large text file

Some ideas

use autodie, 3 argument open, lexical file handles

use autodie;
open my($stuff), '<', 'in.txt' ; # with autodie, no need to "or die"
... <$stuff> ...
close $stuff; # with autodie, no need to "or die"

post a runnable program, not fragments, see How do I post a question effectively?
document said program (expected input, expected output, how the actual output differs from expected), so it makes sense to a stranger like me :)
for example, you say no error output information, but the line in large line number is defective, like below:
but then you don't explain the format, or how your output is defective

This entire reply is anti-helpful, serving only to distract from the simple, one-line solution to the OP's problem: the "N" format to pack is 32-bit, so it won't work with offsets larger than 2^32. The "Q" format is 64-bit, so it will.	[reply]

Really? If moritz makes the same suggestion, minutes before I do, its helpful. If davido asks for clarification, minutes after I do, its helpful. A few minutes later, its clear moritz misunderstood the original question, I guess asking for clarification was helpful after all. A few minutes later, cafeblue clarifies the missing details. A few hours later Eliya answers the question. A few more hours, you show up, to call my reply anti-helpful and as as serving only to distract from the simple, one-line solution to the OP's problem. Anti-helpful? How would you classify your posting, redundant?	[reply]
