Formatting IOS dump data

Format an SVC, stand-alone, or SYSMDUMP dump with the IOSCHECK subcommand to produce diagnostic reports about IOS. z/OS MVS IPCS Commands gives the syntax of the IOSCHECK subcommand and describes the contents of each report. z/OS MVS IPCS User's Guide explains how to use the IOSCHECK option of the IPCS dialog.

The UCB parameter on the IOSCHECK subcommand, for example, formats the unit control blocks (UCB) for a list of device numbers.
