Hi Jess,
Tied variables might work, but I was also browsing CPAN this afternoon, and
I noticed that there is a whole SAS module under "Commercial Software". I
have no idea what it does, but you might find it interesting to look at.
Thanx,
Smiddy

Certainly. The MLDBM module found on CPAN is good for this. It has a few
caveats on usage, which are described in the documentation.

Hashes can be stored in dbm files. Also you can use Data::Dumper to
create a string that contains valid Perl syntax to create a give data
structure. You can then write that string to a data file. When you
need that data again you can read the file back into a string and eval
it. See perldoc -
Just to verify, since you didn't specify, You're not loading the entire file
to memory before you start working with it, are you? For example:
open(BIGFILE,"log.tmp");
@bigfile = ;
probably wouldn't be a great idea.
open(BIGFILE,"log.tmp");
while(){
do something to each line
