Since
the
starting address
of
Monitor I Z-0 13A is set
to
$
0000
, relocatable addresses and object codes
in
the
assembly list can be assumed
as
absolute addresses and object code, respectively.
This assembly list
is
provided for reference, only and
the
Sharp Corporation can assume no responsi-
bility for answering a
ny
question
about
it.
Note t
hat
this
monitor
differs from
the
monitor
program included in
the
BASIC interpreter.
