I have some questions considering use of handles with Mac Applications.

1)	What is the best way to allocate a chain without fragmenting the
	memory? Using handles is not as simple as you might think at first
	- You need to allocate master pointers with MOREMASTERS for all your
	handles in the main datasegment (#1), and you won't know the amount
	of handles in a chain forehand. I know that when all of them are
	in use system calls moremasters again to allocate more pointers, but
	it can fragment memory!

2)	How can I store a TEstylehandle entirely into a file? Is
	the following (written in pseudo-code) enough:
	...
	...
	FSWrite n bytes , pointer (TEstylehandle^)
	...
	...
	Quite rough code, but - I hope - understandable!
	The idea is that I can edit several pieces of text having
	only one TEHandle allocated!

Are there any technical notes considering the questions?
