That's what files are for. Why would you write something into a file if
you didn't plan to read it at some time?

Well, why would you write something to a file and then read it back into
the program if you already have the information in the program to begin
with?

It all depends on what the OP meant with "later". I have seen code like
        
        system ("myprog > temp.txt");
        open (TMP, '<', 'temp.txt');
        @result = <TMP>;

Here the programmer writes information to a file and later reads it back
into the program, but unless there are very special circumstances
probably nobody would call this good code.

The OP already clarified that this is not what he was doing but that he
was dealing with log files. But that detail was missing in the original
post.

I've done this in the past. It was the only way I could find at the time
to get the output of an external process under Win98...

...I guess those probably count as 'very special circumstances' :).

Clearly your ESP::PSI module is far supperior to mine. That's OK, I
don't mind.
But I don't how see how continuing this discussion would serve any
useful purpose. But again, maybe my crystal ball has failed me.
