Some restrictions became from space reasons necessarily, so e.g. the 
renouncement of a view into the OS-ROM and the renouncement of a 
possibility of producing Compoundfiles directly.  Whether as 
disadvantage one feels depends on the work style.  The author never 
pursues OS call by debuggers, but on the basis the OS listing and 
rather works with handy individual parts than with a wild code 
monster, which a Compoundfile is even.  Finally it is not a trouble to
bind after conclusion of all work and tests the parts with a DOS to a 
Compoundfile.  

4.1.  Command sentence of the debugger the command sentence limited to
the most necessary orients itself strongly at the editor assembler 
cartridge of Atari and therefore corresponds to many other debuggers 
so that a tabular listing of the instructions is sufficient.  With the
instruction input no blanks may be inserted, the instructions must 
immediately after the prompt begin.  To the input only the input line 
stands for order, but in the output-area ALL changes are along-logged.
All inputs understand themselves in hexadecimal.  Storage locations or
registers without change of contents can be jumped over by omitting a 
value.  Example:  Cl00<A,,4D changes $$IO0 up $$OA and $102 on $4d. 
thereafter stands the internal address pointer on $103.  Contents of 
1101 remain unchanged.  

With all commands address specifications can be omitted, the debugger 
used then the internal address pointer and/or one the clear 
representation favorable final value.  The expenditure knows at any 
time with the keys S (stop) and Q (of far ones) to be continued and/or
continued.

Here for reasons of the legibility inserted blanks must be omitted 
during the input.  The PC cannot be changed due to the special 
internal treatment with R<, but only with G. of the sector buffers for
SW and rudder is identical to the internal sector buffer for the DOS 
and from the MEMORY manager to SD100 in the frozen address area is 
reflected, where a treatment with the debugger can take place.  
Physically it is not!  

Changes in the hardware register express themselves after thawing out,
finally the frozen address area are only manipulated, and not, how 
with conventional debuggers, the material address area!
