DEL
<name>
which
will
cause
the specified file to be deleted.
If the
obJect file from the assembly process example above is to
be
deleted,
for
instance,
the following command line
~ould
be
entered:
DEL TESTPRQG.LX
It should be noted that the suffix is specified.
Since
the
DEL
command
is a general purpose command,
like the
DIR
commandl no default value for the

is
supplied.

2.8.5 EXBIN -- Creating program load module
The
EXBIN.
command is used to
coryveT't
the
obJect
file
fT'om
the
assembly process (assumes no OFT REL OT' OPT ASS
in
source file)
into
a
file
~hose
contents can
be
loaded
into
memory
ror
execution.
MDOS
can
only
load programs into
memory that are
in
memory-image
files.
Thus,
the
EXBIN
command
must
be invoked after an
~ssembly
process to CTeate
the loadable file.
The
fo~mat
of the command
line
for
the
EXBIN command is:
EXBIN
<name:>
The
<name/
speci~ied
on the command line is the name o¥
the EXbug-loadable obJect
file
created
by
the
assembler.
Only
the
rile
name
need be specified.
The de¥ault suffix
"LX"
is automatically supplied by the EXBIN command.
A
file
in
the
memory-image
format
will
be
created by the EXBIN
process that has the same fila name as <name>,
but
has
the
su¥fi~
"LO"
to
differentiate its file type.
The following
command line
EXBIN TESTPROG
will convert
the
file
TESTPROG.LX:O
to
its
memory-image
equivalent
TESTPROG.LD:O.
Thus,
the processes of editing.
assembling,
and obJect rile conversion can all
be
performed
on
a
rile
by
only. T'eferring to its file name.
