Chapter 4. Utility Functions
Overview of Library Utilities
The HSC contains utility functions that provide you with ways to manage library
resources. Primary utility functions include:
• library CDS maintenance
• control of library cartridges
• control of scratch volumes
• preparation of reports covering library activity.
In addition, utilities contain the following attributes:
• Most are submitted to the SCP for execution, but some require or allow special
environments.
• Utilities submitted as batch jobs to the SCP require the use of special SCP JCL
(SLKJCL) statements.
• Specific utility functions are requested by special utility control statements which
define the function and supply all required parameters; these are distinct from JCL
statements.
