A page is a unit of memory allocation in OpenVMS.
For VAX, a page is equal to a block, 512 bytes. For Alpha, page size varies between 8192 bytes (8 kilobytes) and 64 kilobytes and can be determined using SYS$GETSYI or F$GETSYI() PAGE_SIZE item. For Integrity, page size varies between 4096 bytes (4 kilobytes) and 4 gigabytes (GB) and can be determined using SYS$GETSYI or F$GETSYI() PAGE_SIZE item.
