System Utility Programs
System utility programs manipulate collections of data and system control information_
The system utility programs are:
I EHATLAS, which
is
used to assign alternate tracks when defective tracks are
indicated_
IEHDASDR, which
is
used
to
initialize direct access volumes
or
to
dump
or
restore data.
IEHINITT, which
is
used
to
write standard labels on tape volumes.
IEHIOSUP, which
is
used
to
update entries
in
the
supervisor call library
(VSl only).
IEHLlST,
which
is
used
to
list system control data.
IEHMOVE, which
is
used to move or copy collections of data.
IEHPROGM, which
is
used
to
build and maintain system control data.
IEHUCAT, which
is
used to update an OS catalog to
the
level
of
a
VSAM
catalog (non-VSAM data sets). (VSl only)
IFHSTATR,
which
is
used
to
select, format, and write information
about
tape errors from the IFASMFDP tape or
the
SYS1.MAN data set.
A system utility program
is
executed or invoked through the use
of
job control
statements and util ity control statements.
DATA SET UTILITY PROGRAMS
Data set utility programs manipulate partitioned, sequential, or indexed sequential data
sets provided
as
input
to
the programs- Data ranging from fields within a logical record
to
entire data sets can
be
manipulated. The data set utility programs are:
IEBCOMPR, which
is
used
to
compare records
in
sequential
or
partitioned
data sets.
IEBCOPY, which
is
used to copy, compress, or merge partitioned data sets,
to
select
or
exclude specified members
in
a copy operation, and
to
rename
andlor replace selected members of partitioned data sets.
I EBDG, which
is
used to create a test data set conSisting of patterned data.
I EBEDIT, which
is
used to selectively copy job steps and their associated
JO B statements.
IEBGENER, which
is
used
to
copy records from a sequential data set
or
to
convert a data set from sequential organization
to
partitioned organization.
IEBISAM, which
is
used
to
place source data from an indexed sequential
data set into a sequential data set
in
a format suitable for subsequent
re-
construction.
IEBPTPCH, which
is
used to print or punch records
that
reside
in
a
se-
quential
or
partitioned data set.
IEBTCRIN, which
is
used
to
construct records from the input data stream
that
have been read from the
IBM
2495 Tape Cartridge Reader.
I EBUPDTE, which
is
used
to
incorporate changes
to
sequential
or
partitioned
• data sets.
Data
Set utility programs can be executed as jobs
or
can be invoked as subroutines by
a
calling program.
