NPAGEVIR

   NPAGEVIR defines the maximum size to which NPAGEDYN can be
   increased. If this value is too small, the system can hang.
   If NPAGEVIR is too large, the result is a penalty of 4 bytes
   per extra page on VAX and 8 bytes per extra page on Alpha and
   Integrity servers.

   For the benefit of OpenVMS VAX systems with limited physical
   memory, AUTOGEN logs a warning message in its report if NPAGEDYN
   exceeds 10 percent of physical memory or if NPAGEVIR exceeds 33
   percent of physical memory.

   AUTOGEN also limits its own calculated value for NPAGEDYN to 20
   percent of physical memory, and limits NPAGEVIR to 50 percent
   of physical memory. These calculated values are adequate for
   most workstations and systems with 16 or fewer megabytes of
   physical memory. If your system requires a larger value, you can
   override the AUTOGEN calculated values by setting higher values
   in MODPARAMS.DAT.

   NPAGEVIR has AUTOGEN and GEN attributes.
