It is the most full-blown case of security by obscurity that I've encountered. I wrote to Bill and he confirmed that he used a Pascal program to "scramble" his code into hundreds of little pieces connected by indirect JMPs! I, in turn, wrote a little Ctl-Y routine to call INSTDSP one instruction at a time, *following* JMPs instead of LISTing them--which straightens out the scrambled code. ;-)Classic. What a pro! It's quite nice you can converse with him about it!
He was pleasantly surprised that someone was looking at his old code!
Ingenious solution you've come up with too. Chess across decades. ;-)
The deprotector always has the advantage, since all the protector's moves have already been made, and the deprotector gets to shift strategies. ;-) -michael NadaNet networking for Apple II computers!
