PROUNLOK is a ONE-TIME process to remove Prolok from your program.
It is an improvement over and replaces PROKEY.COM (a resident program).
Using DBASE as an example:
1. Isolate PROUNLOK.COM and DBASE.EXE onto a separate subdirectory
or floppy. You don't need the original floppy to run this.
2. Type PROUNLOK DBASE
If everything works ok you will wind up with a DBASE.EXE that's
about 6K smaller and minus the Vault (Prolok) code. It's the .EXE
the publisher started with. You can copy and run it as you like.
Has been tested with dBase III (1.0), Framework, Realia and Excel.
If it doesn't work on your program, consider these possibilities:
1. Your program isn't protected by Prolok. Do a TYPE on the
.EXE file. Vault always puts their copyright notice in the
first 200-300 bytes in plaintext (unencrypted). Note that
Ashton-Tate quit using Prolok in Jan 85. They may go back.
2. Is there a procedure for installing your program on hard disk?
If so, you have the new, rewritten, Prolok. This program will
not work.
Kudos to the Lone Victor (PROLOK.UNP) for finding the right intercept
point. I automated the process.
History:
V1.0 3/01/85 (First release)
V1.1 3/02/85 Wraparound when size of .EXE > 64K
V1.2 3/30/85 Was not writing final short sector to .EXE
If my program works for you, I would appreciate a contributation of $25.
