- $ SHOW MEM 'knows' if a swap/pagefile is the primary swap/pagefile or
- not. If it is the primary file it can come up with a valid name for it since
- it knows where VMS will look for it. If it's not, it only has a FID.
- It will try to translate this into a filename but if the running process
- does not have read access to the pagefile (it shouldn't for unprivileged
- users, else you have a security hole) it can't translate this into a name
- so you get the 'file name not available' message. Same as $ show dev/fi <disk>
- will show error messages instead of filenames if you don't have read access to
- those files.
