Command Line path

hello,
Quick question. How can I make the command line (i'm not sure if its DOS becasue its XP) recognize one of my own directories as one of its default paths. ie - i made a CAT program for windows/dos, and i would like to be able to execute and use it from any directory i'm currently in, and i don't really want to put it in C:\Windows\system32 or any other of the default paths, so that i can find and debug my own programs easier withought going to those huge directories and finding them. Thanks for the help.

you can change your path variable. Look up how to change it in xp I think it's like control panel something. Then you would set it to something like c:\bin; %path%

Start->Settings->Control Panel->Advanced->Environmental Variables->System Variables->Path:

Add ;C:\Mypathtosearch

thanks, the 2nd one worked.
Now i'll be an efficient MACHINE
