Free Expanded (EMS) 16 M (16,777,216 bytes)
Largest executable program size 588 K (602,512 bytes)
Largest free upper memory block 0 K (0 bytes)
MS-DOS is resident in the high memory area.
Windows 2000和Windows XP示例輸出:
655360 bytes total conventional memory
655360 bytes available to MS-DOS
633872 largest executable program size
1048576 bytes total contiguous extended memory
0 bytes available contiguous extended memory
941056 bytes available XMS memory MS-DOS resident in High Memory Area
mem /f
顯示常規的內存空閑量。

MS-DOS is resident in the high memory area.
Windows 2000 and Windows XP example output:
655360 bytes total conventional memory
655360 bytes available to MS-DOS
633872 largest executable program size
1048576 bytes total contiguous extended memory
0 bytes available contiguous extended memory
941056 bytes available XMS memory MS-DOS resident in High Memory Area
When using the mem /c command from a DOS window in Windows, no upper blocks are seen, as shown in the above example. In Windows 0 bytes are shown because Windows reserves all global upper memory blocks for Windows.
MS-DOS 6.2 and above does not accept or recognize more than 64 MB of ram when typing mem.

mem的問題
在Windows中的DOS窗口中使用mem /c命令時，不會看到上層塊，如上例所示。
在Windows中顯示0字節，因為Windows為Windows保留了所有全局上部內存塊。
當輸入mem時，MS-DOS 6.2及以上版本不接受或識別超過64 MB的ram。
When using the mem /c command from a DOS window in Windows, no upper blocks are seen, as shown in the above example. In Windows 0 bytes are shown because Windows reserves all global upper memory blocks for Windows.
MS-DOS 6.2 and above does not accept or recognize more than 64 MB of ram when typing mem.
