It depends what operating system you are using.
I'm using windows 2000
In my C:\WinNt\system32\ directory there is the command interpreter which used to be command.com or at least parts of it in DOS of old ie. version 6 and less
the command interpreter is named cmd.exe
if you make a copy
then search for the text continue in it using a hex editor you will find the text you wish to change.
The only catch is that it is stored in unicode (ie. as two bytes pre character so instead of searching for "continue" you have to search for c0n0t0i0n0u0e0 where '0' is the character with a hex value of 00h
so do a seach for the following hex values
63 00 6f 00 6e 00 74 00 69 00 6e
and you will find a couple of cases.
Change the text to what you want and see if after running your new copy of cmd.exe the message say what you want.
Now all you have to do is call the newcmd.exe when you run everthing with the new pause.
the easiest way is to create a shorcut with the following
"C:\newcmd.exe" /c a.bat
a.bat contains
