APPENDIX H. 1
Each
symbol
in
the symbol table requires eight bytes.
Thus,
if the minimum of 16K bytes
of
memory
is
used,
the
M6800 Assembler can accommodate about 300 (decimal) symbols.
For
more
details about the M6800 Assembler,
the "M6800
Co-Resident Assembler Rererence Manual" should be
conSUlted.
The following enhancements have been made in the MDOS version
of
the
M6800
Assembler
over
the
~pecifications
in
its
reference manual.
The
symbols
may
contain the special characters period
<. ) and dollar sign
($)i
however,
the dollar sign may not
be
used as the first character of a symbol.
The
END
directive
has been changed so that it now has
the
follo~ing
rormat:
END
C<expression>J
where the value of the optional
<expressicn~
will
be
placed
into
the
59 record of the object file.
This record is used
to specify the starting execution address of the object file.
If
no
expression
is
specified,
the value of zero will be
used.
Like other MDOS commands,
the ASM command
is
sensitive
to the BREAK and CTL-W keys of the system console.
The
object
file
produced
is
in
the
EXbug-loadable
format.
The file must be converted into a memory-image
file
before it can be loaded from the diskette into memory."
