System utility programs

System utility programs are used to list or change information that is related to data sets and volumes, such as data set names, catalog entries, and volume labels. Most functions that system utility programs can perform are performed more efficiently with other programs, such as IDCAMS, ISMF, or DFSMSrmm.

Table 1 is a list of system utility programs and their purpose.

Table 1. System Utility Programs
System Utility	Alternate Program	Purpose
*IEHINITT	DFSMSrmm EDGINERS	To write standard labels on tape volumes
IEHLIST	ISMF, PDF 3.4	To list system control data
*IEHMOVE	DFSMSdss, IEBCOPY	To move or copy collections of data
IEHPROGM	Access method services, PDF 3.2	To build and maintain system control data
*IFHSTATR	DFSMSrmm, EREP	To select, format, and write information about tape errors from the IFASMFDP tape

*These programs provide functions that are better performed by newer applications, such as ISMF or DFSMSrmm or DFSMSdss. IBM continues to ship these programs for compatibility with the supported older system levels.

The system utilities listed next support user data sets allocated with any valid combination of the following dynamic allocation options: XTIOT, UCB NOCAPTURE, and DSAB above the line.
