... in which it is written....
System parameters are global variables that you can tune in a variety of ways:
Assigning new values using dbx. (Values established by dbx are only temporary;
they are always lost the next time the system is booted.)
Establishing values by editing the system configuration file
(/usr/sys/conf/system_name) or the param.c file
(/usr/sys/system_name/param.c).
Establishing values for configuration attributes in the sysconfigtab file
(/etc/sysconfigtab). (Configuration attributes correspond to global variables in
the system configuration file and the param.c file.)
The latter method is preferred because it requires only a system reboot to put new values
permanently into effect; whereas, using the other methods is either only a temporary
solution (dbx method) or requires a kernel rebuild and a system reboot (system
configuration file or param.c method). Kernel rebuilds can be difficult and time consuming
and should be avoided whenever possible.

Thanks also to Terry for directing me to sysconfig -q vm. I have to agree
with him, some decent documentation would help. It probably exists
somewhere but life is too short to play hunt the needle in the haystack.
