2 newbie questions

[Bee]

hello all,

I've just start my learning on perl, and recently still learning some basic syntax.
So I hope my question is still making sense.

I am now learning about how to write files and wondering is that possible
to inserting / overwriting bytes in files ( text / binary ). and I am on Win32.

Also, I am still learning how to use perldoc, and I found something is tutorial...
so.. would anybody tell how many tutorials inside and what are they ?

thank a lot

Yes -- See "perldoc read" and "perldoc seek". Basically, you find where in
the file you want to replace text (the offset) then replace from there.

There are tons of online tutorials, but you should start with the perl
documentation first. 'perldoc' has several forms, bascically,

perldoc PACKAGE or DOCUMENTATION (example above)
perldoc -q "some search criteria (q = query)
perldoc -f "some function" (example: perldoc -f print)

Start with 'perldoc perl'.

Hope that gets you started.
