===== Eat this line.....PLEASE!! ======
I have two 'basic' questions:
1. Can anyone please tell me how to 'hide' a program
which should be executable through the autoexec.bat?
2. I just bought a program called "Mind Prober" from
The Human Edge.
I put it on my hard disk (copy a:*.* c:), but when
I start this program from the hard disk, the program
in the opening screen looks at the a: drive.
Obviously it can't find it, and tells me that the
program (on the hard disk) is an illegal copy.
So I made another copy (from a: to b:) and stuck this
copy into the a: drive with the same result.
Now, my question is: Can anyone please tell me how to do
this in basic? I'm not interested in unraveling this
program, but I would like to use this routine in my
own programs.
THANKS!

Here are two small programs, called hide.com and unhide.com, that will hide or unhide any file or directory. If an executable file is hidden, It will still be found. I have hidden my autoexec.bat, config.sys, and command.com in the root directory without any problems. ========== CUT HERE ========== begin 644 hide.com M#A^[@``NB@<*P'06F`/80R[&!P"Z@@"X`4.Y`@#-(>L,D(S(CMBZ,@&T"<TA MN`!,S2$-"E5S86=E.B!(241%(%MD<FEV93I=6W!A=&A<769I;&5S<&5C+GAX F>`T*"@<D```````````````````````````````````````````` ` end ========== END HIDE.COM ====== ========== CUT HERE ========== begin 644 unhide.com M#A^[@``NB@<*P'06F`/80R[&!P"Z@@"X`4.Y``#-(>L,D(S(CMBZ,@&T"<TA MN`!,S2$-"E5S86=E.B!53DA)1$4@6V1R:79E.EU;<&%T:%Q=9FEL97-P96,N F>'AX#0H*!R0````````````````````````````````````````` ` end ========== END UNHIDE.COM ==== These are in standard uuencoded format. uuencode and uudecode should be available on your system.

These disks are physically marked with a "signature" area, so making a copy of the disk won't help (as you found out). These floppies are available at your local computer store in small quantities (2?) so you can protect your own programs. You may find that protecting your software is not beneficial. Think about how your users will react to having to use a key disk on a hard- disk based system before you make a mistake. ---- Dan Crimmins University of Illinois at Urbana-Champaign Computing Services Office - Micro Consulting Dept.
