I found a (Jva focused) page in my links over the weekend: http://mindprod.com/jgloss/unmain.html

I realy like it. ::)

>Some useful examples of obfuscation can be found from the entries in the [url=http://en.wikipedia.org/wiki/International_Obfuscated_C_Code_Contest]International Obfuscated C Code Contest[/url]. Of course, you can't apply exactly the same techniques (VFP being a line-oriented language wheras C is pretty much free-form using statement terminators to indicate end of statement rather than end of line), but you can definitely glean some ideas from some of the entries. As by an earlier post, you can utilize variable names which use letters and numbers of similar appearance to make it difficult to decode. You can also utilize #include statements to redefine behavior.

>I don't know if we could do something that I'd done in the days of BASIC/BASICA/GWBASIC -- use a program to manipulate the tokenized code to change the variable names throughout the program in a way so that if code was reparsed, you'd end up with a bunch of syntax errors (what the program did is change the variable names to be identical to keywords within the tokenized file). The program would work fine just as long as you didn't try to export to ASCII or edit anything.
