The S/390 Integrated Server provides several OS/2 utility programs as part of the software. These are
located in the \P390 subdirectory. You can use these when you are writing your own device manager or if
you want to accomplish a task without using one of the System 390 Integrated Server interactive
interfaces. These utilities are:

ALC.EXE OS/2 Utility
ALC allocates and initializes files for use by the P/390 as FBA DASD. ALC can also display information
about an existing volume, and it can change a volume label. ALC can be used to allocate files such as
paging, spooling, or TDISK as part of an installation process, instead of using the interactive process with
the P/390 Configurator.
The ability to change a volume label is useful when you are moving volumes between systems or
reconfiguring a system. It is especially useful when the volume must have a specific name, such as VM
CP-owned volumes, which may require you to change the CP configuration if the name changed.
See "CKDALC.EXE OS/2 Utility" on page 244 for a utility to allocate count-key-data DASD files.
