MEM [/CLASSIFY | /DEBUG | /FREE | /MODULE module name] [/PAGE]

/CLASSIFY or /C Classifies programs by memory usage. Lists the size of programs, provides a summary of memory in use, and lists largest memory block available.
/DEBUG or /D Displays status of all modules in memory, internal drivers, and other information.
/FREE or /F Displays information about the amount of free memory left in both conventional and upper memory.
/MODULE or /M Displays a detailed listing of a module's memory use. This option must be followed by the name of a module, optionally separated from /M by a colon.
/PAGE or /P  Pauses after each screen full of information.
