I apologize in advance for the elementary level of my questions.  I
just got my Mac, and I didn't know who to turn to!

(1) How does one store different defaults for MacWrite (tabs, margins,
fonts,...) than the ones it comes with?

(2) How does one have a program (e.g. in pascal or basic) see a
MacPaint document as an array? (presumably that's the way the data is stored
internally, as  a bit map, but I don't seem to be able to open the
file with anything other than MacPaint itself).

(3) Is there a MacWrite with max size of documents larger than the
standard one (128K, I think) ?

(4) Anybody out there with experience with the Koala MacVision digitizer?
(I have questions to ask before buying. In particular, is there any way
of capturing grey levels?  How about color information?)

Thanks,
