To learn about the innards of the Macintosh OS.
To obtain detailed assembly listings and cross reference maps of a program.
To learn programming techniques used by other programmers.
As an adjunct to the Jasik Debugger to produce symbolic 'map' files
(called 'snit' or 'snt' = Saved Nosy Tables files) so that ANY program
can be debugged symbolically.
This capability is presently used by my Debugger to give you symbol
information when you are executing System code on 68K or PPC Macs.
In addition to the above, Nosy will also let one annotate procedures
with comments and 'enhance' the disassembly, etc.
As Nosy and 'The Debugger' use a common disassembler, one should
look at the disassemblies
in the Debugger features section.
