Sorry about the lack of documentation. I found that the first three parameters had the most effect for this quite old DOS TSR from the early 1990s. As to its placement, if you are using VDMSound's auxillery program LaunchPad, you would put the statement:

C:\Utils\MouseCTL.com 3,4,5,6,7,8,9,10\

Here's the manual for MOUSECTL:

MOUSECTL Michael J. Mefford
Adjusts mouse sensitivity
-------------------------------------------------------

Purpose
-------
Provides multiple sensitivity settings for achieving more precise and smooth control of IBM and MicroSoft mice.

Format
------

MOUSECTL [n ... n | filename | /U]

Remarks
-------
MOUSECTL is a memory-resident utility that can be loaded either at the DOS prompt or as part of an AUTOEXEC.BAT file. It can be used only with IBM or Microsoft mouse drivers and must be loaded after either MOUSE.SYS or MOUSE.COM. MOUSECTL can be deinstalled by entering the command with the /U switch.

The optional n parameters consist of up to eight "multiplier" values between 0 and 32767, which are used to modify the mouse sensitivity. The default values are 5,6,10,15,22,30,50,70. Other values for n may be entered using either a space or a comma delimiter. The n values are entered into a look-up table from left to right; if less than 8 numbers are entered those already in the table remain in force.

The range values represent the number of mickeys (1/200th-inch increments) the mouse actually moves during its 25-millisecond reporting period. The multiplier values (n) are divided by 10 and then multiplied by the range value to determine the adjusted number of mickeys reported to the application program. For example, an actual motion of 5 mickeys, multiplied by 0.6 results in 3 mickeys being reported, slowing the mouse movement to obtain more precise control for drawing. A movement of 30 mickeys in one 25-ms period will be multiplied by 5.0, so that 150 mickeys will be reported, moving the cursor very rapidly for page scanning.

Note
----
Because Microsoft Windows loads its own mouse driver, MOUSECTL cannot be used with Windows utilities or with programs (such as Pagemaker) that must, rather than may, be run under Windows.

What's weird is that it's working in XP, although with DOS software. But mickeys? *falls over laughing*

So the 8 parameters are all equivalent? It looks like it just multiplies them all together and devides by 10^8.

Right. I don't understand it either. 🙄

Maybe it an overflow-avoidance thing. Or a backwards compatability and accretion thing.
