A CI string variable cannot exceed 1024 characters and thus the
result could be truncated. Truncation is evident by checking wordcnt() <
total. E.g.
setvar x VOLINFO('@','VolSets')
if wordcnt(x) < ![word(x,'/')] then
# truncated list...
Examples
:calc VOLINFO("@",
"VOLSETS")
2/MPEXL_SYSTEM_VOLUME_SET
RATVOL_VOLMGT_QASYSXL
:calc VOLINFO("MPEXL_SYSTEM_VOLUME_SET",
"Exist")
TRUE
:calc VOLINFO("MPEXL_SYSTEM_VOLUME_SET:MEMBER1",
"LDEV")

Additional Information
MPE/iX Transient Space Overhead
This consists of the volume space that is used for temporary processes,
such as stacks, heaps and the operating system datastructures.
MPE/iX Virtual Memory Overhead
The virtual memory overhead is the volume space that is allocated for
saving segments of main memory temporarily. This amount of configured
virtual memory space is equivalent to the amount of used virtual
memory space. Virtual memory is allocated only on system volumes;
there is no virtual memory on private volumes.
MPE/iX Directory Space Overhead
Directory space is area on system and non-system volumes reserved for
accounting information. It consists of the directory space used for
permanent files.
MPE/iX File Label Overhead
On MPE/iX, each volume has its own label table, which contains file
labels and extent descriptors for files that begin on that volume.
MPE/iX transaction management overhead
Transaction management overhead consists of any logging information
that is maintained in order to provide file consistence and file recovery.
Spool file disk usage
Spoolfile space consists of the volume space that is used by hidden
spoolfiles. Hidden spoolfiles are not part of the permanent file space.
This space can be found only on system volumes that are configured
with the device class SPOOL. Spool file space is not allocated on
nonsystem volumes.
Total MPE/iX Overhead
This consists of everything on a volume that is not set aside for file
space use. This is the volume space used for operating system
VSVolumeNames the specified volume set.
