aw geeze, you are right Papa Echo, I read right past what gibb said, he is typing that into the "Run" window.

To enter DOS commands, and when you expect some sort of response of text in a window, you need to first open a DOS window. You can't use the "Run" window, because immediately after the command line is acted upon the child window will close. Thus you just see a flash of the DOS window which opened up for that instant.
Also, if you enter some incorrect DOS command, you will never get the chance to read the error message.
So, click Start>All Programs>Accessories>Command Prompt
(alternate method: enter "cmd" into a Run window, that will also open a DOS window.)
In that DOS window type
help | more
(again, that is a vertical bar).
The commands may individually have a way of getting additional help by entering
(where somecommand is the command you want some additional info of how to use the command)
That is generally the nearest help you will find
OR you could try following the command with at least one space
then "?" or "/?" or "-?" or "/h" or "-h"
Sometimes, just entering the command, with no following parameters, will also bring up that same rudimentary help. It really depends upon the code developer of that command. Try any to see what works for that command.
