JCL UTILITIES

IEBCOMPR

Used to compare two sequential data sets, two partitioned data sets or two PDSEs at the logical record level to verify a backup copy. Fixed, Variable, or undefined records from blocked or unblocked data sets or members can also be compared. However, you should not use IEBCOMPR to compare load modules.

IEBCOPY

Can be used to:

   Make a copy of a partitioned data set or PDSE.

   Merge partitioned data sets (except when unloading).

   Create a sequential form of a PDS or PDSE for a back up or transport.

   Reload one or more members from a PDSU into a partitioned data set or PDSE.

   Select specific members of a PDS or PDSE to be copied, loaded, or unloaded.

   Replace members of a partitioned data set or PDSE.

   Rename selected members of a partitioned data set or PDSE when copied.

   Exclude members from a data set to be copied, unloaded, or loaded

   Compress a partitioned data set in place.

   Upgrade a load module for faster loading by MVS program fetch.

   Copy and reblock load modules.

   Convert load modules in a PDS to program objects in a PDSE .

   Convert a partitioned data set to a PDSE or a PDSE to a partitioned data set.

   Copy to or from a PDSE data set, a member and its aliases together as a group

IEBDBG

IEBDG is a data set utility used to provide a pattern of test data to be used as a programming debugging aid. This pattern of data can then be analyzed quickly for predictable results.

IEBEDIT

To create a data set containing a selection of jobs or job steps. These jobs or job steps can be entered into the job stream at a later time for processing.

IEBGENER

Can be used to:

   Create a backup copy of a PS, a member of a PDS or PDSE or an HFS file.

   Produce a PDS or PDSE, or a member of a PDS or PDSE, from a PS or HFS.

   Expand a PDS by creating members and merging them into the existing data set.

   Produce an edited sequential or partitioned data set or PDSE.

   Manipulate data sets containing double-byte character set data.

   Print sequential data sets, members of PDS or PDSEs or HFS files.

   Reblock or change the logical record length of a data set.

   Copy user labels on sequential output data sets.

   Supply editing facilities and exits for your routines.

IEBIMAGE

Modify, print, or link modules for use with the IBM 3800 Printing Subsystem and IBM 4248 printer modules and stores them in a library.

IEBISAM

Can be used to:

   Copy an ISAM data set directly from one DASD volume to another.

   Create a backup copy of an ISAM by copying it into a PS on a DASD /Tape.

   Create an ISAM data set from an PS.

   Print an ISAM data set.

IEBPTPCH

Can be used to print or punch:

   A sequential or partitioned data set, or PDSE, in its entirety

   Selected members from a partitioned data set or PDSE

   Selected records from a sequential or partitioned data set, or PDSE

   The directory of a partitioned data set or PDSE

   An edited version of a sequential or partitioned data set or PDSE

   A data set containing DBCS.

IEFBR14

Dummy program. Does Nothing.

IEBUPDTE

Can be used to:

   Incorporate source language modifications into PS or PDS, or PDSEs

   Create and update data set libraries

   Modify existing sequential data sets or members of PDS or PDSEs

   Change the organization of a data set from PS to PDS or PDSE, or the reverse.
.
IEHATLAS

Equivalent to Device Support Facility (ICKDSF). Not available now.

IEHINITT

Used to place standard volume label sets onto any number of magnetic tapes mounted on one or more tape units

IEHLIST

A system utility used to list entries in the directory of one or more partitioned data sets or PDSEs, or entries in an indexed or non-indexed volume table of contents. Any number of listings can be requested in a single execution of the program

IEHMOVE

Can be used to move or copy:

   A sequential, partitioned or BDAM data set residing on one to five volumes.

   A group of non-VSAM data sets cataloged in an ICF catalog.

   A volume of data sets.

   BDAM data sets with variable-spanned records.

IEHPROGM

Can be used to:

   Scratch (delete) a data set or a member of a partitioned data set.

   Rename a data set or a member of a partitioned data set.

   Maintain data set passwords.

IFHSTATR

Select, format, and write information about tape errors from the IFASMFDP tape.

My grandfather once told me that there were two kinds of people: those who do the work and those who take the credit. He told me to try to be in the first group; there was much less competition.
