random i/o disk file

[Tom Cloyd]

Am definitely on the steep part of the ruby learning curve. I've
programmed a bit in several other languages. Now I need something like a
random disk file, so I can have a large hash or something like it
available for random access. I've looked in Programming Ruby II, and the
Ruby Cookbook. No info there. I then tried to search the arhives at
http://blade.nagaokaut.ac.jp/ruby/ruby-talk/index.shtml - the search
tool seems not to be working. I then tried to find something with
Google. No go.

I must be thinking about this wrongly, somehow.

So...how does one handle indexed (random) access to a large file - one
too large to have in memory? I can't believe that random/like disk I/O
is not possible in ruby.

Thanks in advance...

t.

It works just like in C....

$ echo thisisatest > test.fil
$ irb=> "sis"

Oh, man, I really DID miss something. What great news. You've made my
day, even though it hasn't really started yet.

Tks,
