I'm attempting to learn how to use the low-level debuggers
fsdb and edebug32, but can't seem to get them to work.
The debuggers aren't crashing; they simply won't budge
from the msdos prompt.

Given the absence of documentation, I am not entirely sure
how they should behave.  Having read FAQ-ch12, searched
through the mail archives, and downloaded djlsr203.zip to
examine the source, my impression is that fsdb and edebug32
are executed from the command line and should go full-screen.
From there you use a series of hot-keys to do things.

However, when I execute them, nothing happens:
D:\djgpp>edebug32
Usage: e:/djgpp/bin/edebug32.exe debug-image [args]
D:\djgpp>fsdb
Usage: e:/djgpp/bin/fsdb.exe [debug args] debug-image [image args]
Options:  -p path    Specify path for source files.
          -d         Enable dual monitor display.
          -s file    Load setup from specified file.

Nor does it work if I try to execute it upon a simple program:
D:\djgpp>gcc hello.c -g -o hello.exe
D:\djgpp>fsdb hello
hello: No such file or directory (ENOENT)
Load failed for image lines

What then is "debug-image", if not the executable?

I am familiar with the commercial low-level debugger SoftICE.
It is loaded like a driver from AUTOEXEC, and sometimes
CONFIG.  Do I need to do something like that for fsdb and
edebug32?  Maybe add a line to djgpp.env?

I am absolutely certain that the overall djgpp package is
otherwise correctly configured because I am merrily writing
c/c++ programs and using gdb.  Hence, I have not included
system information in the email, except to say that it is
running under Windows 95.

I have already searched the web with everything from AltaVista
to Zengine.  Complete, mind-numbed confusion here.
Will someone please point me in the right direction?
