Description
1.
Before
in
v
oking
the
prepro cessor
in
this
mo
de
when
the
program
b eing
prepro cessed
already
has
a
stored
mo
dule,
ensure
that
the
earlier
v
ersion
of
the
program
is
not
b eing
executed.
2.
The
prepro cessor
starts
a
DBE
session
in
the
DBEn
vironmen
t
named
in
the
R
UN
command
b
y
issuing
a
CONNECT
TO
' DBEnvir
onmentName
'
command.
If
the
autostart
ag
is
OFF,
the
DBE
session
can
b e
initiated
only
after
a
ST
AR
T
DBE
command
has
b een
pro cessed.
3.
If
the
DBEn
vironmen
t
to
b e
accessed
is
op erating
in
single-user
mo
de,
prepro cessing
can
o ccur
only
when
another
DBE
session
for
the
DBEn
vironmen
t
do es
not
exist.
4.
When
the
prepro cessor's
DBE
session
b egins,
ALLBASE/SQL
pro cesses
a
BEGIN
W
ORK
command.
When
prepro cessing
is
completed,
the
prepro cessor
submits
a
COMMIT
W
ORK
command,
and
an
y
sections
created
are
committed
to
the
system
catalog.
If
the
prepro cessor
detects
an
error
in
SQLIN,
it
pro cesses
a
R
OLLBA
CK
W
ORK
command
b efore
terminating,
and
no
sections
are
stored
in
the
DBEn
vironmen
t.
Prepro cessor
w
arnings
do
not
prev
en
t
sections
from
b eing
stored.
5.
Since
all
prepro cessor
DBE
sessions
initiate
only
one
transaction,
an
y
log
le
space
used
b
y
the
session
is
not
a
v
ailable
for
re-use
un
til
after
the
session
terminates.
If
r
ol

y
ou
can
issue
the
