What are it's novel features? 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. > Can I look at named variables on the call stack and mess with them? Yes, you can look at named variables, including structs, and modify their values. > Can I break when variable is modified? I'd just like to know what it does. 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. > > What interfaces are there to low level debuggers (eg TMON) or > are they ever needed any more? :-) 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). > > How do precompiled #includes work?

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.
