Subject: Modifying files.

Hi all,

I'm trying to modify a file that has tab delimited fields.  I want to
modify the 4th field within each row.  I can get to the field I want
by using the "split" function operating on \t delimiter... but this
function returns an array right?  It doesn't return a pointer to the
fields?

So if it doesn't return a pointer then how can I modify the field
within the file easily?

a = File.open("blah.txt")
f = (a.gets).split(/\t/)
f[4] = f[4] + "blah"
.... what do I do after this?  How can I write the value back out to
the file?

Thanks,
