dump/restore. IBM removed IEHDASDR in MVS/XA. IEHINITT IEHINITT ("INITialize Tape") initializes tapes by writing tape labels. Multiple tapes may be labeled in one run of the utility. IBM standard or ASCII labels may be written. An example of an IEHINITT program: //IEHINITT JOB ACCT,'LABEL TAPES',MSGCLASS=J,CLASS=A //STEP0001 EXEC PGM=IEHINITT,REGION=8M //SYSPRINT DD SYSOUT=A //LABEL DD DCB=DEN=2,UNIT=(3490,1,DEFER) //SYSIN DD * LABEL INITT SER=123450,NUMBTAPE=3 /* This example will label 3 tapes on a 3490 magnetic tape unit. Each tape will receive an IBM standard label. The VOLSER will be incremented by one for each tape labeled. Each tape will be rewound and unloaded after being labeled. IEHIOSUP Update TTR links for type IV Supervisor Call (SVC) routines in SYS1.SVCLIB. Not applicable to OS/VS2 or later. IEHLIST IEHLIST is a utility used to list entries in a Partitioned Dataset (PDS) directory or to list the contents of a Volume Table of Contents (VTOC). The IEHLIST utility is used to list the entries contained in any one of the following: PDS directory VTOC Catalog (OS CVOL) An example of an IEHLIST program: //IEHLIST JOB ACCT,'LIST PDS',MSGCLASS=J,CLASS=A //STEP0001 EXEC PGM=IEHLIST,REGION=8M //SYSPRINT DD SYSOUT=A //PDS1 DD DSN=xxxx.yyyy.zzzz,DISP=OLD //SYSIN DD * LISTPDS DSNAME=xxxx.yyyy.zzzz,FORMAT /* This job will produce a formatted listing of the PDS directory of the PDS named xxxx.yyyy.zzzz. An example of an IEHLIST program to list a VTOC is very similar: //IEHLIST JOB ACCT,'LIST VTOC',MSGCLASS=J,CLASS=A //STEP0001 EXEC PGM=IEHLIST,REGION=8M //SYSPRINT DD SYSOUT=A //VOL1 DD VOL=SER=vvvvvv,DISP=OLD //SYSIN DD * LISTVTOC VOL=SER=vvvvvv,FORMAT /* IEHMOVE IEHMOVE moves or copies collections of data. However, DFSMS (System Managed Storage) environments are now common, and IBM does not recommend using the IEHMOVE utility in those. A move differs from a copy in that following a move the original data set is deleted, or scratched. Some of the tasks that IEHMOVE can perform include the following: Moving or copying sequential and partitioned data sets Moving or copying multi- volume data sets Moving an entire volume of data sets On the surface, IEHMOVE may seen redundant to the IEBGENER and IEBCOPY utilities. However, IEHMOVE is more powerful. The main advantage of using IEHMOVE is that you do not need to specify space or DCB information for the new data sets. This is because IEHMOVE allocates this information based on the existing data sets. Another advantage of IEHMOVE is that you can copy or move groups of data sets as well as entire volumes of data. Because
