8086 Assembly Debugging with AFD - Advance Full Screen Debug [PART 2 - Advance]

In the last tutorial we have covered some basic features of AFD  to get you started . Lets look at some advance features that will make debugging 16 bit assembly programs less painful.

This image is from last tutorial in which we divided the AFD display into four regions.
1- Registers
2- Disassembly
3 & 4 - Memory Window 1 & 2

The features are explained with examples ( where necessary ) below.

The very first thing that I will write about is how to change content of these regions without typing a command in CMD.

8086 Assembly Debugging with AFD - Advance Full Screen Debug [PART 1 - BASIC]

As most of modern debuggers like IDA, Oledbg and Windbg seems to fail in debugging old 16 bit COM files.  I began researching on different debuggers available today to debug those 16 bit executables ( I am refering to COM files here )

While, doing my research I found a list of debuggers that are available these days to debug 8086 programs. Some of them are listed below

• TR      -  ( no official link available + shareware)
• grdb    -  Kind of an enhanced version of debug.exe ( discontinued after Windows XP )
• Insight - The one with the most user friendly interface

There was another debugger that I couldn't find on the internet and that I used when I wrote my first 8086 assembly program in my university. It is Advance Full Screen Debug a.k.a AFD.
