Command Line Method 2
To
start
debug
using a
command
line, you
must
use
the
following
syntax:
debug
[filename [arglistll
For example, if you specify a filename,
the
following
would
be
a typical
command
to
start
debug:
debug
file.exe
Debug
would
then
load file. exe into
memory
starting at
100
(hexadecimal)
in the lowest available segment.
The
BX:CX regiS-
ters
are loaded
with
the
number
of
bytes placed
into
memory.
If
you
do
include
afilename,
you
might also specify an arglist. An
arglist is a list
of
filename parameters and switches that
are
to
be
passed
to
the program filename.
So
when
filename
is loaded
into
memory, it
is
loaded as if.it
had
been
started
with
a
command
of
the
form,
debug
filename
arglist.
Here,
filename
is
the
file
to
be
debugged, and arglist is
the
rest
of
the
command
line
used
when
debug
calls and loads
filename
into
memory.
Debug Command Information
Each
debug
command
consists
of
a single
letter
followed
by
one
or
more
parameters. Additionally,
the
control
characters
and
spe-
cial editing functions
described
in Chapter
5,
"MS-DOS Editing
and
Function Keys," apply
to
debug
as well.
If
a syntax
error
occurs
in
a debug command, debug
reprints
the
command
line and indicates
the
error
with
a
caret
C)
and
the
word
"Error" as in the following example:
dcs:100
cs:110
1\
Error
Note
that
when
typing commands and parameters you may use
any combination
of
uppercase and lowercase letters.
The
debug
commands are listed below. Following this list,
the
commands
and their parameters are described in
greater
detail.
