COBSR
CO
is
an
NMRL
b ecause
the
source
le
sp ecied
RLFILE.
A
LISTRL
command
on
COBSR
CO
in
the
Link
Editor
will
sho
w
three
separate
ob
ject
mo
dules
in
COBSR
CO,
con
taining
the
en
tries
main
p
,
sub
1
,
and
sub
2
,
resp ectiv
ely
.
These
ob
ject
mo
dules
corresp ond
to
the
three
concatenated
programs
in
COBSR
C,
and
they
can
b e
purged
or
separately
manipulated
in
the
Link
Editor.
If
program
SUB-1
has
an
error,
it
can
b e
recompiled
in
to
COBSR
CO
with
the
command:
COB85XL
SUB1,COBSRCO;INFO="$CONTROL
RLFILE"
As
the
result
of
this
command,
the
mo
dule
con
taining
the
ob
ject
co de
from
program
SUB-1
in
COBSR
CO
is
replaced
with
new
ob
ject
co de.
No
other
mo
dules
in
COBSR
CO
are
c
hanged,
b ecause
COBSR
CO
is
an
NMRL.
Th
us
it
is
not
necessary
to
recompile
all
the
programs
in
COBSR
C
to
x
one
of
them.
(If
the
ob
ject
co de
for
SUB-1
didn't
exist
in
COBSR
CO,
then
the
new
co de
w
ould
b e
app ended
to
COBSR
CO
in
a
new
mo
dule.)
If
RLFILE
is
not
sp ecied,
whether
the
compiler
output
le
is
an
NMRL
or
an
NMOBJ
dep ends
on
le
co de
of
the
ob
ject
le
(if
it
already
exists).
If
the
le
that
COBOBJ
refers
to
already
exists
and
has
a
le
co de
of
NMRL,
the
ob
ject
le
will
b e
an
NMRL.
Ho
w
ev
er,
since
RLFILE
w
as
not
sp ecied,
some
RLFILE
functionalit
y
is
not
enabled.
In
particular,
concatenated
programs,
when
recompiled,
will
b e
put
in
to
a
single
ob
ject
mo
dule
within
the
NMRL.
(Recall
that
if
RLFILE
is
sp ecied,
concatenated
programs
are
put
in
to
separate
ob
ject
mo
dules
in
the
NMRL,
allo
wing
them
to
b e
separately
manipulated
in
the
Link
Editor.)
Example

F
ollo
wing
the
example
ab o
v
e,
if
b oth
programs
SUB-1
and
SUB-2
ha
v
e
errors,
then
the
following
indirect
le
list,
named
COBSR
C1,
w

compile
just
those
t

in
to
the

$INCLUDE

$INCLUDE

SUB-2.
The

is
the
command
to
compile
the

COB85XL
COBSRC1,COBSRCO
RLFILE
is
not
used,
but
the
target
le
COBSR
CO
is
an
NMRL.
This
means
that
COBSR
CO
remains
an
NMRL,
but
the
co de
the
compiler
pro duces
for
SUB-1
and
SUB-2
app ears
in
a
single
ob
ject
mo
dule,
instead
of
t
w

Recall
that
the

compilation
pro duced
an
NMRL
with
three
mo
dules,
eac
h
con
taining
an
en
try
corresp onding
to
MAIN-P
,
SUB-1,
and
SUB-2.
The
second
compilation
results
in
an
NMRL
with
t
w
o
mo
dules.
The
rst
mo
dule,
corresp onding
to
MAIN-P
,
is
unc
hanged,
b ecause
the
main

as
not

The
