IECDSECT,IEFJFCBN,
AND
IEFUCBOB MACRO-INSTRUCTIONS
If
you
want
to
use
the
IECDSECT,IEFJFCBN
and
IEFUCBOB
macro-
instructions,
you
must
either
add
these
roacro-definitions
to
the
macro-library
(SYSi.MACLIB)
or
place
them
in
a
separate
partitioned
data
set
and
concatenate
this
data
set
to
the
macro-library.
This
section
contains
the
following:
•
The
forn,ats
of
the
macro-instructions.
•
The
Job
Control
and
utility
stateroents
needed
to
add
the
rnacro-
definition
to
the
library.
•
The
macro-definition
to
be
added
to
the
library.
IECDSECT MACRO-INSTRUCTION
This
macro-instruction
defines
the
syrrbolic
names
of
all
fields
in
the
work
area
used
by
the
OPEN, CLOSE, TCLOSE,
and
EOV
routines.
Code
this
macro-ins"truction
with
blank
name
and
operand
fields,
and
precede
it
with
a
DSECT
statement.
Note:
The
IEFJFCBN
rracro-instruction
is
used
in
the
assembly
of
IECDSFCT.
The
macro-definition
for
IEFJFCBN
nlust
be
present
in
the
macro-library
(SYSi.MACLIB)
for
successful
definition
of
all
fields
in
the
work
area.
