Thanks to everyone who helped with my last question (disable dos). I
had a great time with my friend. I disabled copy, del, dir, etc. I ren
a lot of the external commands and replaced all these with a file a 
wrote that displayed random messages like, "Error!", "Bad command or
file name." etc. My friend got truely frustrated. It was great. (Of
course I fixed his system once I'd had my fun (and won the bet)).

I have another question: Where are good places to put things you want
called every time the computer is turned on? Autoexec is kinda obvious.
Command.com is going to be the first place he'll look (same friend, no
bet this time). I was thinking of msdos.sys, but I have no idea how to
add something to it. I realize this is complex, so mayby you could just
direct me to a book. Any other ideas would be appreciated. 

Usual disclaimers.

I would have autoexec call a batch file say:   \
note that is chr(255) \ chr(255)
while dos does not like a space in a file name (although B.A.S.I.C. will allow
it) alt 255 is not considered a space (obviously since 32 is the code for that)

by the way you may enter the any character by its code by holding down the alt
key and typing its code on The NUMERICAL key pad.

(this should shak him up pretty good, as I have done it several times before.
)

I've done this before.  Again it requires patching your COMMAND.COM.  Using
DEBUG, search for the string AUTOEXEC.BAT and replace it with your own batch
file, something like TEMPEXEC.BAT.  Write and quit DEBUG.
Next create your file.  Something like this:

     @ECHO OFF
     ...
     your stuff goes here.
     ...
     \AUTOEXEC

Now hide the file using ATTRIB TEMPEXEC.BAT +h

He should have a hard time finding your changes.

Have fun

Bill
