The first, and most noticeable difference is that it requires MultiFinder and
runs in a separate layer, thus giving full compatibility -- something you don't
have with the Pascal product.  The price is the amount of memory required.

Yes, you can look at named variables, including structs, and modify their
values.

I haven't had occasion to see if checkpoints were implemented, so I don't know
the answer to that one.  The nicest feature is the use of popups for popping
back and forth through your calling chain and being able to double click on
fields of structs in the variable window and get a new variable window which
displays what you just double-clicked.

All of the old TMON/MacsBug compatibility is still there, and it is still
occasionally needed (like when trying to traipse through ROM to find out what
is getting trampled).

They are similar to the MPW Pascal $LOAD files in that they have, in symbol
table form, all the information from the include file, thus allowing a quick
load of a single file rather than the multiple #includes with subsequent
processing.
