Mem (Free Memory and Disk Space Display)
Copyright (c) 1990, 1991 by David A. Feinleib
Mem displays the amount of memory free, the largest block of memory
free, and the amount of disk spaces free on drives that you
Mem can stay in front of other applications so that you can see it
while you work.
Additions/Improvements in versions of Mem
- Version 1.00[December 30, 1990]
- Version 1.01[January 5, 1991]
This version included the addition of an alarm which may be turned
on so that the alarm will sound when the amount of free memory is
below a certain number of bytes which you specify.
When the "Display in KB" setting is used, the number is divided
by 1024, instead of by 1000, which gives a more accurate display
of the free KB.
The "stay in front" code was modified slightly so that Mem
will only update its display when necessary.
The setting of the system box (displayed or not displayed)
is now saved correctly.
Context sensitive help was added using the Windows 3.0 help
- Version 1.02[January 25, 1991]
The option of being able to display number in MB, as well as
KB, and Bytes, was added.
- Version 1.11[January 27, 1991]
Mem now requires less memory to run in and can be swapped out
to disk by Windows more easily so that it can take up almost
no memory at all.
The time between updates can now be changed.
You can now set alarms to sound when the disk space of specified
drives goes below the amount you specify (the amount specified
may be different for each drive).
The ability to turn Mem's "Bring To Front" option on and off
The code to write the MEM.INI file after pressing "OK" from
the Preferences dialog box was speeded up.
Requirements for running Mem
- Microsoft Windows 3.0
- Mem (MEM.EXE, MEM.HLP)
Please note that the following directions assume you are using a
mouse.If you are not using a mouse, please refer to your Windows
documentation for equivalent keystrokes.
1. Copy MEM.EXE to your Windows directory or another directory
of your choice.
2. Do one of the following:
Note: Option D is highly recommended over A, B, and C.
A. Click on "File" then "Run..." in the Program Manager menu.
Type MEM.EXE (including the path) in the "Command
line" edit box and click "OK". If you use this option,
you will have to do this every time you want to run
B. Click on one of the program groups in the Presentation
Manager (the "Accessories" group is suggested). Select
"File" then "New..." from the program manager menu.
Select "Program Item" and type MEM.EXE in the
"Command line" edit box. For example, you might type:
C:\WINDOWS\MEM.EXE if that was the directory into
which you had copied Mem.When you want to run
Mem, double click on the Mem icon.
C. On the line that says "load=" in your WIN.INI file,
add MEM.EXE (with the appropriate path). For
example, if you copied MEM.EXE to C:\WINDOWS,
the line would say: load=C:\WINDOWS\MEM.EXE
This option will automatically run Mem each time
you run Windows. This option is especially useful if
you are using Mem to help with software development or
other situations in which you will need to see the
amount of memory/disk space free very often.
D. Do both B and C, which will automatically run Mem
and allow you to run Mem easily if you close it.
To bring up a list of options, click once on the Mem
This will bring up an index of help topics available for

on drives that you select.
Select "Bring To Front" to have Mem stay in front of other
applications; if "Bring To Front" is not selected, Mem
will not stay in front of other applications.
Selecting "Commas" will insert commas as appropriate.
Selecting "In Bytes" will display all numbers in Bytes;
selecting "In KB" will display all numbers in KB;
selecting "In MB" will display all numbers in MB.
Selecting "Alarm when free memory is below" will cause
Mem to sound an alarm if the amount of free memory goes
below the number of bytes you specify in the
You may select to have alarms go off for different drives
when the amount of free space on a specified drive
goes below the number of bytes specified in the edit
box. You may set different amounts for each drive
by selecting a drive, entering the number of bytes in
the edit box, clicking "Alarm when disk space on drive",
using the scroll bar if necessary.
If the alarm sounds, the Mem window will flash at the same
time; to turn off the alarm, click on Mem to give it the
You may change the time between updates by entering the

an index of all help available for Mem. It will also
explain how to use Mem's context sensitive help.

Mem system menu items, holding down the mouse button, and
3. You may access context sensitive help from most
of Mem's dialog boxes by clicking on the "Help" button
if one is displayed.
If you want to "Cascade" or "tile" the open windows, it is useful to
minimize Mem so that it does not get cascaded or tiled. To do this,
click on the system box and select "Minimize" from the menu. Please
note that Mem will take about one-half of a second to minimize itself
since it saves its position on the screen before it is minimized.

icon and then select "Restore" from the system menu.

size by once of two methods:

from the menu.
