RLOAD -- Link ing Loader
The RLOAD
command
combines
relocatable
obJect
files
created
by
the
M6800/M6801/M6805/M6809
Mac~o
Assemblers or
the
M6800
FORTRAN Compiler and produces
an
absolute
obJect
file in either memory-image or EXbug-loadable format.
The
Linking Loader is invoked from the
MDOS
command line
as are other
MDOS
requires
that

RLOAD
Linking
Loader
of

bytes of
RLOAD works basically the same as
described
in
the
"M6800
Linking
Loader
Reference
Manual";
however,
the following
changes have been made in the MDOS version
Or
RLOAD over
the
specifications
in
the manual.
Some
commands
have
been removed from RLOAD since they
were originally
intended
ror
a
c~ssette
version
of
the
Linking
Loader which is no longer supported.
These commands
are:
EXBUG, aI, SRCH, SKIP,
FILE, and MODU.
The
STR,
CUR
(without
backslash
option),
and
END
commands
allow
the use of either a defined ASCT symbol or a
numeric constant to the right of the equal sign.
The default BSCT address that RLOAD will assign is $0020
if
assembly language progT'ams are being linked; however,
the
default address of aSCT will become $0040 if FORTRAN programs
are
linked.
In
addition,
FORTRAN
programs
will
be
automatically assigned memory locations so that DSCT
and
PSCT
fallon even addresses.
Therefore,
the CUR commands with the
backslash option (\) need not be used
when
linking
FORTRAN
programs;
however,
if
the
CUR
command with the backslash
op~ion
is used when linking FORTRAN programs, the
user
must
ensure that the supplied number
is
an even number.
Programs with uninitialized BSCT anoior USCT wiil
no~
De
allocated
space
on
the
diskette
when
an
absolute:
memory-image
fi Ie
is
created;
however, all of the BSCT and
DSCT must
be
uninitialized for this reatUT'e to be of use.
The format of the load
map
is slightly improved over the
examples
shown in the Linking Loader manual.
Each program's
symbols are printed separately,
in
alphabetical
order,
so
that
an
individual symbol can be more easily located in the
printed maps.
