My apologies for being vague,
Imagine a billing statement in text form. There are a number of lines, generally all different lengths before the \n, which I need to alter.
For example, a line may be (literally):

         Joe Bloggs, 1615 Thislane Street\n
[download]

Now imagine I need to replace the address with a piece of text that is longer than the one in the original text - thusly my

substr($f, 20, 30, "This is a new longer address\n");
[download]

will have substr complain 'substr outside string'.
What I want perl to do is say "Okay, its longer than the original string was, thats fine, I don't really care. Honest."

Hopefully this is clearer
