1. opening and writing files...

Heya all!

Me again, this time i'm wondering this: When I open a file for write,
it gets set to 0, I open a file for append, it starts at EOF, I open a file
for update, it lets me seek around, but when I write bytes to the file
at specific points, instead of adding the characters to the file, it
overwrites whatever is there.

How can I get it so that I can seek to a part of the file, and add
characters? Again, I don't have these files in memory (trying to
make the footprint during usage as tiny as possible)

TIA,
