VIRTUALPAGECNT

   On VAX systems, VIRTUALPAGECNT sets the maximum number of virtual
   pages that can be mapped for any one process. A program is
   allowed to divide its virtual space between the P0 and P1 tables
   in any proportion.

   If you use SYS$UPDATE:LIBDECOMP.COM to decompress libraries
   and the VIRTUALPAGECNT setting is low, make sure you set the
   PGFLQUOTA field in the user authorization file to at least twice
   the size of the library.

   At installation time, AUTOGEN automatically sets an appropriate
   value for VIRTUALPAGECNT. The value depends on the particular
   configuration-the type and number of graphics adapters on the
   system, if any exist. You cannot set VIRTUALPAGECNT below the
   minimum value required for your graphics configuration.

   Because the VIRTUALPAGECNT setting supports hardware address
   space rather than system memory, do not use the value of
   VIRTUALPAGECNT that AUTOGEN sets to gauge the size of your page
   file.

   Starting with OpenVMS Version 7.0, VIRTUALPAGECNT has been an
   obsolete parameter on Alpha systems. Note, however, that the
   parameter remains in existence on Alpha and Integrity servers
   for compatibility purposes and has a default and maximum value of
   %X7FFFFFFF. SYSBOOT and AUTOGEN enforce this default value.

   VIRTUALPAGECNT has the AUTOGEN, GEN, and MAJOR attributes.
