ABOUT MEM.EXE v 3.0
CHANGES: Mem now evaluates whether or not you are operating in a windowed
environment, using the fastest possible video access. DOS redirection
is not allowed. Scrolling is improved.
MEM is a general memory analysis program. It tells you your DOS speed (not
processor speed), breaks down your memory arenas, tells you the size and
amount available of all disk drives, expanded memory, and system memory.
Syntax:
MEM [d:]
^ last valid drive in your system
LAST DRIVE
MEM looks at all the drives (from A: to Z:). Sometimes, this is not
desirable. For that reason, you may specify the last valid drive on the
command line. Also, you may enter "SET LastDrive=d:" into DOS for the
same purpose.
DISPLAY
Mem splits the screen into three section. The three sections are DOS
speed, Drive/Memory size, Memory arenas.
DOS SPEED: This operation finds out how many times DOS can calculate the
current time in one second. This is a pretty good test to see how much
processor time is stollen by resident programs and routines.
DRIVE/MEMORY SIZE: Each drive is accessed and displayed for disk size and
amount still available. If the drive is not active, then it is simply
skipped. Then expanded memory is surveyed. WARNING::: Be sure that
CMOS know whether you have expanded memory (AT machines only). Then the
amount of system memory available to COMMAND.COM is displayed. The
final piece (amount of system memory is available) is calculated and
displayed.
MEMORY ARENA: COMMAND.COM splits your memory up into blocks (arenas).
Each arena is owned by a program that you have executed. MEM finds this
arena and tracks through the arenas. You find out the hex paragraph
number on which the arena is located and it's size. If a multitasking
environment is in place, then it will also track most of that
environment too (although it isn't very useful).
