4.  The debugger a debugger by machine code connoisseur used around 
object code directly in the memory for error tracing to work on 
changes and improvements.  In the environment of a Freezers that has 
special advantages, however also a few principle-conditioned 
disadvantages, which can be gone around by the correct function.  

The largest preference/advantage is certainly that that with the 
frozen system condition can be worked.  Thereby the impression 
develops quasi with a second Atari in the first, stopped Atari " 
in-sees " and change being able, whereby the stop can be waived at any
time again.  Debuggers without Freezer have to fight here with 
difficult problems.  since it alone by their internal requirement at 
RAM and input/output action the system condition constantly change.  
The technical term for it is " trashen ". which for " to garbage 
transforms " stands.  

A normal debugger needs the information, which the program which can 
be worked on can have put down there for its own function RAM and 
trasht.  Even if the debugger is more complex equipped (by own RAM) 
trasht it still the hardware register of ANTIC, POKEY and GTIA.  The 
OS Shadows ignores the Player Missile graphics and the sound 
production and by many programs is anyway deactivated.  A restart of a
program is by the getrashten hardware register usually only after very
toilsome detailed work, if at all, possible.  Refrained from it to 
offer debuggers without Freezer no possibility, (not readable!)  
Hardware register to select one does not approach thus to the written 
values also if the register were not getrasht by the debugger.  

With the debugger built in the TURBO- FREEZER XL one approaches to all
information about the system condition.  Hardware register contents 
(genuine contents, not the returned status value) can be read in the 
I/0 range and changed when desired, without having to fear crashes.  
since the changes only to the frozen program refer!  Likewise can be 
worked at will in the entire RAM-AREA (also under the OS ROMs), 
without something is possibly getrasht or falls.  

In addition come different advantages, which result from the working 
environment of the TURBO- FREEZER XL.  With the loading and memory 
possibility for frozen programs and the DOS functions can be tried out
changes without long Umladerei immediately and be cancelled also easy 
again if necessary.  Wiederspenstige code monster, which can overwrite
while the loading of parts of the DOS and hardly be worked on in 
conventional way loses to their-frighten.  

A pair of disadvantages gives it however also.  **abend** by that with
the freeze condition work, change thus only after the thaw out effect 
show, will it pedantic, e.g. in the disk work.  After thawing out the 
program is again in full action, thus is a start in another place than
the freezing point in some cases only after careful switching off via 
the frozen hardware register possible
