The DCL command SHOW MEMORY/FILES displays information about
the page and swap files existing on your system, including file
names, sizes, and the amount of space used. For example:
$ SHOW MEMORY/FILES System Memory Resources on 19-JAN-2001 13:35:26.58
Swap File Usage (8KB pages): Index Free Size
DISK$PAGE_DUMPS:[SYS0.SYSEXE]SWAPFILE.SYS;2
1 7992 8248
Paging File Usage (8KB pages): Index Free Size
DISK$PAGE_DUMPS:[SYS0.SYSEXE]PAGEFILE.SYS;1
254 13722 16496
Total committed paging file usage: 4870
The total committed paging file usage is the number of pages
in the system that require pagefile space for paging. It can be
bigger than the total number of pagefile pages that are available
because it is unlikely that all the required space will be used
for paging at one time.
