ASM3870 -- M3870 Cross Assembler
The ASM3870 command
processes
sourc~
program
statements
written
in
the
M3870
Assembl~
Language.
The M3870 Cross
Assembler,
ASM3870,
translates these source
statements
into
object
programs
that can be executed by the M3870 Emulator,
EM3870.
The
M3870
Cross
Assembler
is
invoked
from
the
MDOS
command
line
as
are
other
MDOS
commandsi
however,
the Cross
Assemble~
re~uires
that the system has a
minimum
or
20K bytes
of memory.
The format of the command line is:
ASM3870
<name l>C,<name 2>, ... ,<name nJJ Li<options>J
where <name i>
are
the names of source files.
Each file name
in the list is in the standard
MDOS
file name format
<file name> (.<suffix»
C:<logical unit number>J
The default values of "SA" and "0"
are
used if
<suffix:>
and
<logical
unit
number)
are
not
explicitly entered.
Up
to
twenty file names can
be
accommodated by the assembler.
The
<options> may be one or more of the
options
listed
in
the
following
table.
All
options
except
those that
cont~ol
the
destination
of
the
source
listing,
the
destination
of
the
object
rile,
and the printing
Or
e~ror
messages on the printer if no
listing
is
desired,
can
be
specified
Trom
within
the
sou~ce
program
with
the
OPT
directive.
Certain
options
are
automatically
used
as
a
default
condition.
These
conditions
can
be
~eversed
or
overridden by preceding the option letter with
a
minus
sign
(-).
The
follo~in9
options
are
recognized by the assembler:
