Figure
7
shows
the
arrangement
of
input
for
an
RPG
compilation.
If
the
compile-and-execute
function
is
used,
a
halt
occurs
and
the
halt
code
1D01
is
displayed
in
the
E-S-T-R
fields
on
the
CPU
console
when
the
compilation
of
the
RPG
source
program
has
been
completed.
The
I/O
devices
required
for
execution
of
the
com-
piled
program
must
now
be
prepared
and
started.
The
tape
drive(s)
used
for
the
work
tape(s)
during
compilation
may now
be
used
for
data
files.
If
the
object
program
requires
card
input,
tables
(if
any)
must
precede
card
data
files
when
both
are
read
from
the
same
device.
Note
that
card
data
files
must
be
terminated
by
an
end-of-file
card.
However,
an
end-of-file
card
must
not
be
placed
behind
a
card
table
file.
To
initiate
execution,
press
the
start
key
on
the
CPU
console.
If
the
compilation
is
not
to
be
followed
by
an
execution,
a
halt
does
not
occur
and
the
next
job
is
executed.
PROGRAMMED
HALTS
A
number
of
programmed
halts
may
occur
dur-
ing
the
compilation
and
execution
of
pro-
grams
written
in
the
RPG
language.
The
halt-code
displays
and
the
associated
restart
procedures
are
described
in
the
section
g£Q~amm~~=Halt~i§E1EY§_~~£
.,Restart
Prgcedure.§.
Several
other
halts
can
occur
during
the
execution
of
RPG
object
programs.
These
halts
occur
when
an
arithmetic
operation
is
performed
on
an
invalid
packed-decimal
operand.
They
are
identified
~y
an
opera-
tion
code
displayed
in
the
U-L

on
the
CPU
console.
The
following
codes
may
be
displayed:
DE,
F8,
F9,
FA,
FB,
FC,
or
FD.
When
one
of
these
halts
occurs,
the
job
must
be
discontinued.
The
following
steps
must
be
taken
to

MESSAGES
During
the
co~pilation
of
a
program
written
in
the
RPG
language,
the
RPG
compiler
causes
a
number
of
messages
to
be
listed
on
the
printer
(SYSLST).
Heading,
diagnostic,
and
information
messages
may
be
printed.
For
a
list
of
these
messages
and

DESCRIPTION
OF
OUTPUT
The
output
obtained
from
an
BPG
compilation
consists
of:
a
program
listing
and
printed
messages
if
the
printer
has
been
assigned
to
SYSLST;
the
object
program
contained
in
punched
cards
if
a
card
punching
device
has
been
assigned
to
SYSOPT;
the
object
program
deck
on
tape
in
card-
image
format
if
a
tape
drive
has
been
assigned
to
SYSOPT.
If
the
compile-and-execute
function
is
used,
the
output
of
the
user's
problem
pro-
gram
is
obtained
in
addition
to
the
output
of
the
compilation
as
described
