        '''
        This step does multiple things:

             - makes backup copies of SYS1.PARMLIB members that will be changed, creates
               member IEASYS00 in SYS1.PARMLIB, During IPL, the values coded in IEASYS00 are
               used to customize the MVS 3.8j environment.  Several of the parameters
               contained in IEASYS00 are simply pointers to other members of SYS1.PARMLIB.
               Many of the parameters may be overridden at IPL time, but the IPL process is
               greatly simplified if the most frequently desired settings are coded in this
               member.

             - creates member IEAAPF00 in SYS1.PARMLIB, IEAAPF00 specifies the load module
               libraries from which authorized programs may be executed.

             - creates member SMFPRM00 in SYS1.PARMLIB, SMFPRM00 contains parameters related
               to System Management Facility, which collects and records information about MVS
               and the programs that are executed under its control.

             - creates member IEALOD00 in SYS1.PARMLIB, IEALOD00 specifies load modules that
               contain part of the operating code for MVS which are to be loaded and fixed in
               real storage.  These modules are so frequently executed, fixing them in storage
               can improve the performance of the system.

             - creates COMMND00 in SYS1.PARMLIB, COMMND00 contains operator commands which are
               to be executed automatically upon the completion of the IPL.

             - creates SETPFK00 in SYS1.PARMLIB, SETPFK00 contains settings for the console
               Program Function Keys.  Commands associated with the PFKeys here may be
               executed simply by pressing the associated PFK on the MVS console.

             - creates LNKLST00 in SYS1.PARMLIB, LNKLST00 contains load module libraries which
               are to be automatically searched for load modules executed in batch or under
               TSO.

             - creates VATLST00 in SYS1.PARMLIB, VATLST00 specifies the Volume Attributes to
               be associated with all regularly used DASD volumes.

             - creates PARMTZ in SYS1.PARMLIB, PARMTZ specifies the offset from GMT to
               establish local time.  I have set mine up for the Central Time zone in the
               United States; you may wish to modify this for your geographic location before
               you submit this jobstream.

             - deletes SYS2.LOCAL.LPALIB, This library was created by SYSGEN00 to provide
               local SVC modules during System Generation.  It is no longer needed, so this is
               a good place to delete it.

             - allocates and catalogs SYS2.LINKLIB, SYS1.LINKLIB is the main load module
               library and is created during System Generation.  However, it is not a good
               idea to add your own load modules to that library, so we create SYS2.LINKLIB to
               have a place set up to receive any programs you write locally.

             - allocates and catalogs SYS2.PROCLIB, Likewise, SYS1.PROCLIB is the system's
               catalogued procedure library, but it is not a good idea to add your own
               catalogued procedures to that library, so we create SYS2.PROCLIB for local use.

             - allocates and catalogs SYS2.CMDLIB, As SYS1.LINKLIB is to batch load modules,
               SYS1.CMDLIB is to TSO load modules.  SYS2.CMDLIB is created to be a repository
               for your local TSO load modules.

             - allocates and catalogs SYS2.HELP, SYS2.HELP corresponds to SYS1.HELP -
               SYS2.HELP will contain 'help' (syntax and operand usage instructions) for your
               local TSO load modules.

             - creates member JES2 in SYS1.PROCLIB, Although a basic JES2 catalogued procedure
               member was created by SYSGEN02, a more customized one is created here,
               specifically to utilize/incorporate the SYS2.PROCLIB allocated (three bullets)
               above.

             - creates member CLEARDMP in SYS2.PROCLIB, There are three dump datasets
               allocated on MVSRES to receive system dumps when a catastrophic error occurs.
               If all three of these fill up (are used) the system will not be able to be
               started, so you need to be able to clear these datasets as they are used.  This
               procedure, which may be started from the console, clears and initializes dump
               datasets.

             - creates member CLEARERP in SYS2.PROCLIB, When hardware errors occur, an entry
               is made in SYS1.LOGREC (the environmental error recorder dataset).  This
               dataset will hold a finite number of entries.  This procedure, which may be
               started from the console, clears SYS1.LOGREC.

             - creates member COMPRESS in SYS2.PROCLIB, When library (Partitioned) datasets
               receive many updates, they frequently become in need of reorganization.  If
               left to the extreme, they may exhaust all of their extents.  This procedure,
               which may be started from the console, can be used to compress any partitioned
               dataset, reclaiming unused extents.

             - creates members SMPASM, SMPASML, SMPAPP, and SMPREC in SYS2.PROCLIB, These
               catalogued procedures are used to receive, assemble, assemble/link, and apply
               user modifications and PTFs.

             - copies the members created above - SMPASM, SMPASML, SMPAPP, and SMPREC - into
               SYS1.PROCLIB on START1. We need these to use the System Modification Program to
               update the target system from the MVS Starter System.

             - adds macro IHADVCT to SYS1.MACLIB. This macro acquired from one of the datasets
               on the MVS3.8j optional materials tapes  (MVS Optional Materials Tapes) is
               required for some USERMODs to assemble correctly.

             - allocates and catalogs SYS1.UMODMAC, SYS1.UMODCNTL, SYS1.UMODSRC, SYS1.UMODOBJ,
               and SYS1.UMODLIB, These datasets are used to hold user modifications.

             - allocates and catalogs SYS1.CDS, SYS1.CRQ, and SYS1.SMPCDS, These datasets are
               used to record and track modifications to the target system.

             - initializes SMP for target system's environment.

             - allocates and catalogs SYS2.CONTROL, Some catalogued procedures need control
               cards, and, since control cards cannot be included in catalogued procedures, we
               create this library to hold those type of datasets.

             - adds CLS TSO command and help text for the command, CLS is a short program
               (from CBT 430, file #300) that simply clears the screen for a TSO user.  It is
               compiled into SYS2.CMDLIB with the HELP text placed into SYS2.HELP.

             - adds SETPFKEY batch load module and an execution procedure, This program (from
               CBT 249, file #295) equates operator console commands to the Program Function
               Keys on MVS consoles.  It is compiled into SYS2.LINKLIB and a procedure to
               execute the program is placed into SYS2.PROCLIB.  In a previous step there was
               a START command set up for this program in COMMND00 and PFKey definitions were
               placed into SYS1.PARMLIB(SETPFK00).

             - adds ZTIMER batch load module, execution procedure, and parameter member, This
               program may be used to display reminders or execute MVS operator commands on a
               scheduled or periodic basis.  It is compiled into SYS2.LINKLIB and a procedure
               to execute the program is placed into SYS2.PROCLIB.  In a previous job there
               was a START command set up for this program in COMMND00.  A set of commands is
               placed into SYS2.CONTROL(ZTIMER) for use by the STARTed process to periodically
               clear JES2 queues of non-processed output.

             - adds CLIP batch load module and execution procedure, This program is used from
               the console to relabel (clip) offline DASD volumes.  It is compiled into
               SYS2.LINKLIB and a procedure to execute the program is placed into SYS2.PROCLIB.

             - creates a list of modules to fix in the Link Pack Area in SYS1.PARMLIB, The
               member containing the list is simply copied from another member supplied by IBM
               and could have been utilized as it was, but by creating a copy of the member
               contents, custom modifications may be made to the 'active' copy without losing
               the original set supplied by IBM.

             - submits a job to load into the SMP datasets the specifications for the
               generated MVS 3.8j system and JES2.

             - It is necessary to load the specifications of the new system (acquired from the
               Stage 2 jobstreams which were stored on a work DASD volume) and JES2 so that
               future modifications may be properly integrated into the system.

             - creates member IKJACCNT in SYS1.PROCLIB, This member specifies parameters which
               define the individual TSO Users' address spaces.

             - creates member NET in SYS1.PROCLIB, This procedure is executed to start VTAM.

             - creates member TSO in SYS1.PROCLIB, This procedure is executed to start TSO.

             - allocates and catalogues SYS1.VTAMLST, This library will contain specifications
               for VTAM.

             - creates member ATCSTR00 in SYS1.VTAMLST, This member specifies VTAM parameters.

             - creates member ATCCON00 in SYS1.VTAMLST, This members specifies the tables to
               VTAM for TSO applications and local 3270 terminals.

             - creates member APPLTSO in SYS1.VTAMLST, This member specifies the logon table
               for all local 3270 terminals.  (8 defined initially, you would add more here if
               you need more 3270 terminals to use concurrently)
