Utilities
A few examples
of
utility functions and
the
control statements
that
must be prepared
to
execute them follow.
IBCDASDI
In this example, a
3330
volume
is
initialized for later use as a system residence
volume. An IPL program
is
included
in
standard TXT format.
The
example follows:
INIT JOB 'INITIALIZE
3330'
MSG
TODEV=1403,TOADDR=OOE
DADEF TODEV=3330,TOADDR=l50,IPL=YES
VLD NEWVOLlD=Pl0000,OWNERID=BROWN,ADDLABEL=2
VTOCD STRTADR=2,EXTENT=7
IPLTXT
(IPL program
text
statements)
END
The
control statements are discussed below:
DADEF specifies
that
a
3330
volume
is
to
be initialized and specifies
the
channel number and
unit
number. An IPL program
is
to
be included.
VLD specifies a volume serial number and owner identification for the
volume
to
be initialized. It also specifies
that
space
is
to
be allocated
fo'
two
additional labels.
VTOCD specifies
that
the
volume table
of
contents
is
to
begin
on
track 2
and
is
to
extend over nine tracks.
END specifies
the
end
of
IPL
program
text
statements. Because
IPL
text
is
included,
END
begins
in
column
2.
IEHDASDR
In this example, alternate tracks are
to
be assigned for three suspected defective tracks
on
a
3330
volume.
The
example follows:
IIDASDR3 JOB
II
EXEC PGM=IEHDASDR
IISYSPRINT
DD
SYSOUT=A
'/VOLUME
1
DD
UNIT=(3330 .. DEFER),DISP=OLD,
II
VOLUME=(PRIVATE .. SER=(333000))

TODD=VOLUME1,TRACK=OOAOOOO7
TODD=VOLUME l,TRACK=01010002

The
control
statements
are discussed below:
Page 6-14
VOL
U
MEl
DD
defines a device
that
is
to
contain
the
3330
volume
(333000).
SYSIN
DD
defines
the
control data set, which follows
in
the
input stream.
The
GETALT statements specify
the
ddname
of
the
DD
statement
defining
the
device
on
which
the
3330
volume
is
mounted.
The
GETAL T statements
specify
the
relative track addresses
of
the
tracks for which alternates are
to
be assigned.
