- Well, actually, the startup process only writes the active parameters to
- the current if parameter WRITESYSPARAMS is set to 1. This is the default
- condition; however, if you want all SYSBOOT changes to last for only the
- time they're used, and the next reboot to go back to normal, you can set
- this to 0 in MODPARAMS.DAT.
-
- This is one of a rare few parameters that aren't used in compiled code,
- but only in DCL; I don't think it's used ANYwhere except in startup
- procedure VMS$INITIAL-050_VMS.COM. NOAUTOCONFIG is another, and there are
- a couple more.
