Simply
tell
the

If

to
a

If

file
can
be
compressed

An

can
then
be
written
in

for
an

using
a
production
IODF.
Note:
An
IOCP
input
file
that
was
created
by
HCD
without
PCHIDs
must
be
migrated
back
into
HCD
after
PCHID
numbers
have
been
added
to
the
file
by
the
CHPID
Mapping
Tool.
An
IOCDS
can
then
be
written
from
a
production
IODF
or

can
be
built
for
the
